Flood Warning and Latest Update

We are receiving record amounts of rain and flooding. At present, there has been 9" of rainfall in the OKC area. Many streets are closed, including in and out of Will Rogers World Airport. Water rescues are being attempted in several locations. A rescue boat is now at one location where the passengers of the vehicle have been bailing water out with a bucket for the past three hours. Local TV stations are requesting you stay home unless evacuation is necessary. They are preparing to open the flood gates at Lake Overholser, which may cause low lying areas to flood even more.

Winter Weather Update 3-20-10 2140

Current conditions at the Spencer Mesonet site include temperatures at 28 degrees and winds from the north-northwest at just under 15 mph creating a windchill of 16.6 degrees. Attached graphic products include Updated Snowfall Totals, anticipated Conditions Tonight and Sunday Predictions.

Latest from the National Weather Service:

An upper level low will move slowly east along the Red River tonight. Light snow wrapping around the storm system will line up from north to south along the Interstate 35 corridor. An additional one to three inches of snow will fall near I-35 and eastward through Sunday morning. Flurries will end farther west...but wherever there is snow falling or already on the ground...brisk northwest winds will continue to create some blowing snow and reduction to visibility. Conditions will improve slowly on Sunday. Greater improvement will come Sunday night and Monday as dry and warmer weather moves in behind the storm. Another weather system will arrive near the middle of next week...producing mainly rain.

We will continue to monitor and provide updates as available and necessary.

Major Winter Storm for northern OK*** Blizzard like high winds expected behind the front into Saturday

REPORTED BY GREG WHITWORTH

Models are finally coming to some agreement about the location, timing and impact of the final winter storm of the season. This storm has the potential to put OKC in the record books as the snowiest winter ever if OKC can get 4 1/2 inches.
The 0Z NAM has come a little more in line with the previous GFS runs as far as location and timing of this storm are concerned. For Oklahoma City, I am thinking 2-4 inches, not the "similar to the record blizzard" predicted on TV, at least not in Oklahoma City. Blizzard like conditions will occur due to the winds, but the snowfall amounts don't look as high until you get northeast of Tulsa. However, keep in mind drifting due to high winds may give the appearance of more than 4 inches in OKC.

Location:
Snow will fall northeast of a line from near Lubbock to Abilene, TX and across nearly the entire state of Oklahoma. The only area that is not expected to see much if any snow is south of a line from Frederick to Ardmore to DeQueen, AR.

Amounts:
The most significant snows will fall north of I-40, with the heaviest snow by far impacting areas from Tulsa into southwest and central Missouri, where nearly a foot of snow is expected, northeast of Claremore, OK into Missouri. 1-3" north of a line from Altus to Ada to northern McCurtain Co. This includes the southern
sides of Oklahoma City. 1-3" across the western panhandle from Guymon west.
3-5" north of a line from Elk City to Bethany to Chandler and from Chandler to Checotah to Van Buren, Arkansas. Also 3-6" from east of Guymon across the eastern Texas panhandle. 5-8" north of a line from Gage to Stillwater to Muskogee to Tahlequah 7-12" from northeast of Ponca City to Tulsa to north of Tahlequah
Nearly a foot across far northeast OK, eastern Kansas, western Missouri but south of Kansas City and Columbia where about half a foot of snow is expected.

Timing:
By 1 pm, the front should extend from Cherokee to Erick, through much of northwest OK. Showers and thunderstorms, some heavy to severe, may develop by 3 pm from near Hobart to Ponca City. This is ahead of the cold air. Tornadoes do not appear to be a threat, however gusty winds and large hail appear likely. The storms should move northeast. Vertical velocity fields from the NAM model indicate the strongest storms may occur southwest and south of OKC from near Fort Cobb to Norman.

The front extends from Ponca City to just west of OKC to Altus by 7 pm. The front should clear the Oklahoma City metro area during the 9 pm hour.

Snow should begin in northwest Oklahoma by 7 pm, and extend from near Ponca City to west of Altus by 1 am Saturday. A band of sleet for possibly 2-3 hours will accompany the changeover to snow. The changeover to sleet should extend from Pawnee to Oklahoma City to Frederick by 4 a.m. Saturday, with snow beginning in this area near sunrise.

At sunrise, the changeover to sleet then snow should extend from Tulsa to west of Ardmore. By this time, the front should extend from south-central Missouri to Fort Smith, AR to Dallas, TX. By 1 pm, the changeover should extend from east-central Missouri to far northwest Arkansas to south of McAlester, with snow pushing into the Arkansas River valley by sundown.

Blizzard like winds of 30 to 50 mph appear possible just behind the front. Expect road closures to be common across the northern 3 rows (deep) of counties, starting Saturday afternoon. The winds should gradually subside in western Oklahoma by sunset on Saturday.

Snow will taper off from West to east, ending in the panhandle by 11 am Saturday, and ending
from Ponca City to west of Oklahoma City to Lawton by sunset Saturday evening. Snow should
end in Oklahoma City by about 2 am Sunday morning. This is when the trouble begins.

The snow stalls across eastern Oklahoma and remains there through much of the night east of a line from Ponca City to just east of Oklahoma City to Ada. This will cause heavy accumulations, especially across northeast Oklahoma where heavier bands are expected closer to the track of the low. Snow will continue across northeast Oklahoma and northwest Arkansas, including Muskogee, all areas east of Tulsa, and staying mainly south of the Missouri River, through Sunday night going into Monday, at midnight. The duration of this event would also favor very heavy accumulations, probably of disaster declaration levels,across much of southwest Missouri, southeast Kansas and northeast Oklahoma north and east of Tulsa.

Winds will finally die down in Central Oklahoma by around noon on Sunday when the system begins to pull away.

Winter Storm Watch

Try not to get too excited about Spring just yet; it appears another significant Winter-like blast is heading our direction for Friday evening/night into Saturday. I have attached three graphic products from the National Weather Service for your viewing and below is the latest information, also from the National Weather Service:


Despite warm temperatures Thursday and Friday, much colder air will move into the area late Friday, and a strong storm system will develop over the high plains and move toward the southern plains on Saturday. High temperatures on Saturday will be 20 to 30 degrees cooler than Friday and blustery north winds will occur creating cold wind chill readings. Areas of accumulating snow appear likely. The track of the storm system is still uncertain, so it is also uncertain where the heaviest snow will fall. Anyone with travel plans this weekend is strongly encouraged to keep up with the latest weather forecasts. Before the weather turns back to winter, strong thunderstorms will be possible along the front.

It appears that a Winter Storm Watch may be issued by the National Weather Service, but the extent and specific location is yet to be determined. We will continue to monitor the situation and provide updates as necessary.

Weather Update 1-29-10 0925

Although additional amounts of freezing drizzle and light snow were recorded overnight, we have not experienced the magnitude of icing as originally predicted for our area. Road crews continued clearing and treatments throughout the night, however as additional bands of freezing precipitation passed through the area early this morning, additional accumulations on roadways and exposed surfaces were experienced. Snow continues to fall throughout the area with anticipated accumulations of up to three inches predicted.

State-wide road conditions reports indicate “slick and hazardous” through all but southeastern Oklahoma. Travel is discouraged throughout our area. Reports of power outages are becoming more prevalent, including in some specific areas of the metro, however no wide-spread outages in the metro right now. Larger outages are reported in southwestern, southern and now southeastern portions of the state. We are not receiving significant reports of downed tree limbs in the metro as of yet, however, as the precipitation continues to fall, particularly if wind speeds increase, additional outages, falling lines, broken poles and tree limbs will compound the problems and potential for outages. Attached graphics from the National Weather Service depict a storm update and predictions for today.

From the National Weather Service –

Light snow will continue across northern and western Oklahoma early this morning. While western, southwestern Oklahoma and north Texas will see areas of freezing drizzle and freezing rain. A transition to snow across central and southwestern Oklahoma and western north Texas with 1 to 3 inches of snow possible. Travel is discouraged and even walking outdoors can be hazardous due to slick and ice covered surfaces and the potential for falling tree limbs. Precipitiatioin is expected to end and winds diminish later this afternoon and evening. Temperatures wil remain cold through Sunday.
