Severe Weather Expected

As many of you know, Saturday marks the anniversary of the F5 tornado in Oklahoma. This tornado occurred May 3, 1999 so we are all watching the weather very carefully. If you would like to see a few pictures of the damage, you can view them and read other weather related information at my site, Stormspotter. Org.
Bonnie (stormspotter)

The following weather report comes to you from Greg Whitworth, Fox 25 TV and is used with permission.

** Severe Weather expected across central and eastern OK Thursday **

There are very few changes from yesterday's forecast. Fire danger will be high today and tomorrow across western Oklahoma due to strong southerly winds. Winds will be stronger on Wednesday. Moisture return on Wednesday is weak and there is a formidable cap in place with no lifting mechanism even though a dry line will be edging into the western counties.
A low stratus deck may creep up on the low level jet on Thursday morning, setting the stage for a humid day. The low level jet will be present the next few nights. A shortwave kicks out from the "vort bowl" (positioned over southwest Kansas) mentioned yesterday and will cross across Oklahoma, possibly slightly negatively tilted \ as we head into Thursday afternoon. CIN looks weak and CAPE could be up to 3,000 j/kg. Helicity is most impressive during the earlier part of the day but looks modest enough to produce rotating storms Thursday evening. The dry line will set up near I-35 or Highway 81 during the afternoon and some clearing may occur just ahead of the dry line. A triple point around the Enid-Ponca City-Stillwater area will connect the dry line to a cold front draped northeast to southwest from eastern Kansas to west-central Oklahoma. NAM and GFS suggest storms may form first along the cold front in southeast Kansas but I wouldn't rule out first initiation along the dry line as we have seen several times in the past. It is possible the storms might wait until they are just east of OKC to become severe. Of course this is going into "unfavored chase territory" quickly where the hills and trees become the primary landscape.

The cold front will bring highs in the lower 70s in OKC for the weekend. Several shortwaves rotate northeast out of Texas and across Oklahoma Sunday through Tuesday. One arrives around 9 a.m. Sunday, another 9 a.m. Monday, with a third around 4 a.m. Monday. With an uncapped airmass and ridging staying just north of us, it appears we will have the ingredients in place for a widespread rain and thunderstorm event (probably of the non-severe variety). This is just what western Oklahoma needs! Rain could last through Monday and possibly even Tuesday. I have started dropping high temperatures during this time frame to account for this.

Looking down the road, it still appears severe weather could return sometime late next week.

OKC 82 55/83 63/84 51/72 45/71 46/66 46/65 44/68 42/72 53/79 62/77 50/62
pops: 40% Thursday, 40% Sunday, 30% Monday, 20% Tuesday, 20% next Thursday, 10% Saturday.
Windy Tuesday-Thursday, Breezy Sunday & Monday, Thursday and Friday next week.

Possible Severe Weather and Frosty Nights

** Severe Weather Possible Thursday **
** More Frosty Nights Possible **

A very interesting morning was played out with temperatures falling below freezing in parts of western Dewey County and Buffalo. Many other local valleys were down to 33 this morning. Unfortunately this may not be the last time we see these kind of temperatures. There are indications in the models of this repeating around May 6th or 7th and again around May 13th. The latest freeze ever seen in OKC was May 3rd, 1954. The latest freeze dates for much of northwest Oklahoma go into the first and second week of May, so we might be flirting with some records again. We broke a record low in OKC this morning of 35 degrees. By 9 a.m., many locations were already in the 50s as west-southwest winds kicked in.

A weak back door cold front will slide into the northern half of the state today, turning winds to the northeast. This front will have little effect and skies will remain clear. A weak wave passes over tonight with a few clouds. The front will remain hung up from west-central to south-central Oklahoma, south of OKC, for Tuesday. South of the front, temperatures will climb into the 80s with 70s north of the front. Fire danger will be high south of the front the next two days.

The front washes out and lifts northward late Tuesday. This will set the stage for a windy Wednesday with a weak moisture return. High clouds will pass over the state in association with a weak wave of energy. Gulf really opens for business Thursday. Stratus arrives Thursday morning as moisture deepens. The dry line should mix east to near US Highway 81 by afternoon. Meanwhile, a very strong upper storm will pass across Kansas, trailing into Oklahoma.
One problem with this system, as has been the case with the last many, is we keep getting upper right-lower left angled waves of energy shaped like this: /. We need them to be tilted the other direction like this: \ (negatively tilted) to get the nastiest severe weather in general. Positive upper right to lower left tilted shortwaves do not favor significant severe weather. Plus, we keep having waves that are completely rounded. I have termed this feature a "vorticity bowl."

Despite OUN's doomsday sounding forecast discussions of the past two mornings, this event is not so "classical" looking as they lead to believe. I've seen a few events produce significant severe weather without the classical negative shortwave but plenty which have favored widespread "crapvection" (garbage storms with little organization and only pulse severe capabilities). This is what happens when the cap is removed and there's no certain focusing area for storms. We will have a dry line on Thursday though so significant severe cannot be ruled out.

A front moves in behind the dry line and clears some of the moisture out Friday. Nothing seems to be normal this year. The large "vort bowl" is seen with a significant surface low near Sioux City, IA, moving up towards the Great Lakes. This in itself seems quite unusual and may hold our winds in an easterly direction to light and variable through the weekend with slightly below average temperatures. 6Z and 12Z GFS shows a wave of thunderstorms in some sort of northwest flow pattern coming down Sunday, with a high pressure bubble moving in behind it for Monday. This is a flip-flop of the 0Z run and looks much more believable. Models continue to have trouble resolving items beyond day 7 and I have been averaging the runs to come up with a decent handle on the later extended. New 12Z run has a significant shortwave coming out late Monday night into early Tuesday but the surface features do not favor significant severe weather at this time. Next week winds return to the south, favoring the continuation of a stormy pattern. The most interesting day looks to be Saturday May 10th.

OKC 73 47/75 55/82 63/83 53/72 45/71 48/69 49/62 38/68 44/74 53/79 64/83
Breezy Monday-Tuesday, Windy Wednesday-Thursday
Breezy the following week Tuesday-Wednesday, Windy Thursday-Friday (May 8th-9th)
POPS: Thursday 40%, Sunday 20%, the following Thursday 30% (questionable).
Note: May 5th-6th forecast may need some revision after seeing latest 12z run

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 239
CONTINUES.
THE ISOLATED SEVERE THREAT ACROSS THE CNTRL AND NRN PART OF WW 239
SHOULD SLOWLY MOVE ESEWD LATE THIS EVENING. LARGE HAIL AND ISOLATED
DAMAGING WINDS SHOULD BE THE PRIMARY THREATS. ATTM...UNCERTAINTY
REMAINS CONCERNING WHETHER AN ADDITIONAL WATCH WILL BE NEEDED EAST
OF THE CURRENT WW.
LATEST SFC ANALYSIS SHOWS MID 50S F DEWPOINTS ADVECTING WWD ACROSS
THE LOW ROLLING PLAINS EAST OF LUBBOCK. THIS IS LIKELY CONTRIBUTING
TO INCREASING INSTABILITY ACROSS WEST TX WHERE OBJECTIVE ANALYSIS
SHOWS AN AXIS WITH MLCAPE OF 1500 TO 3000 J/KG. IN
ADDITION...FORECAST SOUNDINGS AND RUC ANALYSIS HAVE INCREASED
VERTICAL SHEAR ACROSS THE REGION WHICH MAY BE DUE TO THE PASSAGE OF
A SUBTLE SHORTWAVE TROUGH EVIDENT ON WATER VAPOR IMAGERY OVER NCNTRL
TX. THE INCREASING INSTABILITY AND VERTICAL SHEAR ALONG WITH STEEP
MID-LEVEL LAPSE RATES EXCEEDING 8.0 C/KM ON THE DEL RIO AND MIDLAND

DO PRODUCE TORNADOES.
DISCUSSION...THUNDERSTORMS ARE DEVELOPING ALONG A WARM FRONT ALONG
THE CORRIDOR FROM JCT TO SJT IN RESPONSE TO LOW-LEVEL CONVERGENCE
AND STRONG DAYTIME HEATING. OTHER CONVECTION IS COALESCING OVER THE
SOUTH PLAINS IN ADVANCE OF A STRONG MID LEVEL TROUGH MOVING ESEWD
FROM NM AND NRN TX PANHANDLE. LOW-LEVEL MOISTURE IS LIMITED ACROSS
MUCH OF W TX...BUT STEEP LAPSE RATES ARE STILL SUPPORTING SUFFICIENT
INSTABILITY FOR SEVERE STORMS. DAMAGING WINDS SHOULD BE THE PRIMARY
SEVERE THREAT WITH THE SOUTH PLAINS CONVECTION AS IT ORGANIZES AND
SPREADS SEWD/SSEWD ALONG THE RESIDUAL WARM FRONT. FARTHER S...THE
MORE DISCRETE STORMS SHOULD DEVELOP INTO SPLITTING SUPERCELLS

ALTHOUGH MUCH OF THE DAY WILL BE DRY...A COMPLEX WEATHER SYSTEM WILL

TAKE SHAPE OVER OKLAHOMA AND NORTH TEXAS...BRINGING A CHANCE FOR

STRONG THUNDERSTORMS. AT MIDDAY...SCATTERED LOW LEVEL CLOUD COVER

AND DEEP GULF MOISTURE WAS IN PLACE OVER CENTRAL AND EASTERN

OKLAHOMA...WITH TEMPERATURES IN THE 70S. FARTHER SOUTH AND

WEST...TEMPERATURES HAD WARMED INTO THE 80S WITH SUNNY SKIES.



A JET STREAM DISTURBANCE HAD LIFTED THROUGH NORTHWEST OKLAHOMA INTO

KANSAS...CREATING A SURFACE WIND SHIFT. AT 1215 PM...THE WIND SHIFT

EXTENDED FROM GAGE TO MANGUM AND QUANAH. HUMIDITY WILL FALL RAPIDLY

BEHIND THIS WIND SHIFT...RESULTING IN A DRYLINE THAT IS EXPECTED TO

BECOME EVEN MORE PRONOUNCED BY 2 TO 3 PM. THE DRYLINE IS EXPECTED TO

PUSH AT LEAST AS FAR EAST AS... ALVA...WATONGA AND LAWTON IN

OKLAHOMA...AND ELECTRA AND BENJAMIN IN TEXAS...WITH FURTHER EASTWARD

MOVEMENT POSSIBLE LATER IN THE AFTERNOON.



ISOLATED THUNDERSTORMS ARE EXPECTED TO FORM NEAR AND JUST EAST OF

THE DRYLINE AFTER 3 PM. THERE WILL BE A DISTINCT RISK FOR SEVERE

WEATHER WITH ANY STORMS THIS AFTERNOON. THE NUMBER OF STORMS WILL BE

GREATER TO THE NORTH OF INTERSTATE 40.

BURKE





Additional comments included:



While the forecast has only very slight chances of rain today, and the SPC moderate risk area is north of us into Kansas, we are growing increasingly concerned that thunderstorms will form along a dry line pushing into western Oklahoma. Given the amount of instability and wind shear, any storm that forms will become a supercell fairly quickly and will be capable of producing large damaging hail and even tornadoes.

While thunderstorms are not a certainty, if you see one developing on radar, anticipate warnings to follow soon. I would not be surprised to see a tornado watch issued for parts of our area before 4pm today. Storms will be most likely along and north of Interstate 40, including parts of the OKC metro area.





We will continue to monitor-

STORMS ARE EXPECTED TO DEVELOP/INCREASE ACROSS REGION THROUGH THE
EARLY TO MID AFTERNOON HOURS. WHILE SOME COULD CONTAIN HAIL...THE
SEVERE THREAT GENERALLY IS NOT EXPECTED TO BECOME SUFFICIENT TO
REQUIRE A WW. BUT...TRENDS WILL BE MONITORED.
SURFACE COLD FRONT CONTINUES TO ADVANCE EASTWARD INTO THE UPPER
MISSISSIPPI VALLEY...WELL OUT IN ADVANCE OF STRONGER MID/UPPER
COOLING ASSOCIATED WITH LARGE-SCALE NORTHWESTERN U.S. UPPER LOW.
HOWEVER...THE LEADING EDGE OF A WEAK INITIAL MID-LEVEL COOL SURGE
HAS SPREAD THROUGH MUCH OF THE EASTERN DAKOTAS. WHILE THIS APPEARS
TO LAG THE SHALLOW SURFACE FRONT...FORCING IS PROVIDING THE FOCUS
FOR ONGOING POST-FRONTAL CONVECTIVE DEVELOPMENT NOW SLOWLY SPREADING
IN A BAND EAST OF THE NORTH DAKOTA/MINNESOTA BORDER.
ABOVE THE FRONTAL INVERSION...MOISTURE ADVECTION ALONG THE AXIS OF A
NARROW LOWER/MID TROPOSPHERIC THERMAL RIDGE IS CONTRIBUTING TO WEAK
TO MODERATE DESTABILIZATION. STRONGEST INSTABILITY IS NOW
DEVELOPING NORTH OF THE MID MISSOURI VALLEY INTO THE SOUTH DAKOTA/
MINNESOTA BORDER AREA. THIS IS BENEATH STEEPEST MID-LEVEL LAPSE
RATES...WHERE MODEL GUIDANCE IS SUGGESTIVE THAT FORCING WILL BECOME
INCREASINGLY SUPPORTIVE OF NEW CONVECTIVE DEVELOPMENT THROUGH THE
18-21Z TIME FRAME.
LATEST RUC GUIDANCE INDICATES THAT INSTABILITY FOR LIFTED PARCELS
BASED AROUND THE 700 MB LEVEL COULD REACH 1000-1500 J/KG...
SUFFICIENT FOR VIGOROUS UPDRAFTS CAPABLE OF PRODUCING HAIL. MODEST
CLOUD BEARING LAYER SHEAR PROBABLY WILL MINIMIZE MAXIMUM HAIL
SIZES...BUT GENERALLY SHORT-LIVED ROTATING UPDRAFTS COULD BECOME
CAPABLE OF PRODUCING SOME HAIL APPROACHING OR BRIEFLY EXCEEDING
SEVERE LIMITS.

POSTED: 6:59 am EDT April 18, 2008 UPDATED: 12:02 pm EDT April 18, 2008 INDIANAPOLIS -- Aftershocks as strong as magnitude 4.5 followed a strong earthquake that hit early Friday. LIVE: Earthquake Hits Midwest The USGS Web site said the 5.2 magnitude earthquake was centered in southern Illinois near West Salem, Ill., about 40 miles north of Evansville, Ind., but was felt as far away as Milwaukee, 350 miles to the north. It struck at about 5:37 a.m., WRTV in Indianapolis reported. Aftershocks hit at 11:15 a.m., 10:55 a.m., 9:46 a.m., 9:36 a.m., 9:15 a.m. and 9:03 a.m., the television station reported. The 11:15 a.m. quake, which had a preliminary magnitude of 4.5, was felt in downtown Indianapolis and across southern Indiana. The others were too small for most people to notice. Skyscrapers shook in Chicago's Loop, 240 miles north of the epicenter, and in Indianapolis, 160 miles to the northeast. People in Cincinnati and St. Louis also felt the earth shake. The quake appears to have caused no major injuries or damage, but it had residents across the Midwest talking Friday morning. A resident of Philo, Ill., south of Champaign, said the house was shaking, and the windows were rattling. He said for central Illinois, it was "a big deal." Indiana State Police spokesman Sgt. Todd Ringle said there were no immediate reports of damage in the state, but damage to a downtown building was evident in Louisville, Ky. Ringle said he was shaken out of his bed in the Evansville area by the earthquake. The earthquake was felt as far away as South Bend and Fort Wayne. It was also felt in the Chicago area and parts of Wisconsin. Air traffic was grounded for about an hour at Indianapolis International Airport as the tower was evacuated. All of the runways were checked and were cleared for usage. It shook tall buildings in downtown Indianapolis. Bonnie Lucas, a morning co-host at WHO-AM in Des Moines, Iowa, said she was sitting in her office when she felt her chair move and heard the ceiling creak. She said the shaking lasted about five seconds. Numerous phone calls poured into the WRTV from viewers who felt the earthquake. Geophysicist Randy Baldwin at the U.S. Geological Survey said the quake was "fairly large" for the region, but that it is the type that might occur "every few years." The last earthquake in the region close to the strength of Friday morning's tremor was a 5.0 magnitude in 2002. The biggest on record, a 5.5 magnitude, happened in 1968, causing damage in southern Illinois. Distributed by Internet Broadcasting Systems, Inc. The Associated Press contributed to this report.
