Dry conditions will persist tonight as short range models indicate a generally weak upper level ridge of high pressure shifting eastward across the Western High Plains tonight. Although an attendant cold front is projected to push through western Kansas by mid-day providing increased forcing, little moisture is associated with this system. Low temperatures tonight will not be as cold as a prevailing south to southeasterly low level flow draws warmer air northward into central and much of southwest Kansas. A cold front will push through western Kansas by early afternoon Tuesday allowing colder air to briefly filter back into the area curtailing any significant warm up.
PATCHY FOG WILL CONTINUE TO DEVELOP THROUGH THE MORNING HOURS ACROSS THE RIO GRANDE PLAINS AND ACROSS THE VICTORIA CROSSROADS AREA AS TEMPERATURES CONTINUE TO COOL INTO THE LOW-40S REGION-WIDE. TEMPERATURES WILL BE A BIT WARMER THAN YESTERDAY WITH AMPLE SUNSHINE AND WEAK WARM AIR ADVECTION ALOFT TAKING PLACE. STILL EXPECTING RAIN TO DEVELOP AS A MID-LEVEL IMPULSE DROPS DOWN FROM THE NORTHWEST BY TUESDAY EVENING BUT WITH THE LOW- LEVEL MOISTURE IN PLACE WE ARE EXPECTING MORE CLOUD COVER.
We'll start off with an arctic high pressure system currently overhead and dealing us the coldest airmass of the season so far. Using climatological snow/liquid ratios between 10:1 and 13:1 plus specific humidity values of 3g/kg should yield 1-4 inch snow amounts across the CWA with the highest amounts of 3-4" located under the frontogenesis across the northeast 1/3 of the CWA. An upper level ridge was expected to move into the Central Plains while an upper trough dug southeast into Southern Plains with its attendant weather by-passing us to the south.

A FEW SHOWERS WILL CONTINUE IN THE MTNS AND IN THE FAR SOUTHEAST AS THE INFLUENCE OF A DEPARTING UPPER LOW WANES. CLOUD DECK WILL CLEAR OUT THROUGH THE DAY TODAY AS SHORT WAVE RIDGE BUILDS INTO THE REGION.
Meanwhile, with high pressure over the Inland Northwest, expect widespread stratus with areas of fog for much of the low lands. Models do not expect much clearning expect for the higher elevations. 18Z TAFS: With ridge of high pressure over the region, light winds and abundant moisture in the boundary layer, stratus and fog will be the issue through the period.
FORECAST HIGH TEMPS MAY BE A BIT ON THE HIGH SIDE.
AREAS OF LIGHT SNOW AND PATCHY FREEZING RAIN HAVE BEEN REPORTED AND WILL CONTINUE AS THE IMPULSE TRACKS TO THE EAST. DRIER AIR MOVES ACROSS THE AREA OVERNIGHT AS UPPER RIDGING DEVELOPS.

UPPER TROUGH TO PUSH ACROSS THE PANHANDLES TUESDAY WITH COLD FRONT MOVING THROUGH THE FORECAST AREA TUESDAY MORNING. DESPITE THE COLD FRONTAL PASSAGE TUESDAY. FRONT SHOULD FINALLY CLEAR OUT THE LOW CLOUDS AND ANY RESIDUAL FOG OR FREEZING FOG BY 18Z TUESDAY.
WV Imagery indicates a weak upper level ridge of high pressure moving eastward across the Central and Southern Rockies. Near the surface, a lee side trough of low pressure is slowly strengthening across eastern Colorado. 1) Freezing fog potential this morning. Have areas of freezing fog for the 6 most western forecast counties. A warm front separating the modified Arctic air from downslope warmed air will lift northward today. 3) Freezing fog for tonight. SREF probabilities are quite high from late tonight and into Tuesday morning for dense freezing fog. Forecast soundings are very conducive for freezing fog formation as warm air advection brings higher dewpoints in the region. 4) Lastly, wind chills for Tuesday morning should not be terrible as the winds are expected to be fairly light and mins should be slightly warmer with the aforementioned waa pattern.
AN EXPANSIVE HIGH PRESSURE CELL IS CENTERED OVER THE MID-MISSISSIPPI RIVER VALLEY.

though cold with arctic high pressure in place. VFR conditions will prevail today with arctic high pressure in place. Expect the clouds to break up some during the day today, but even with some sunshine, much of northeast Oklahoma and far northwest Arkansas will remain below freezing today. There is some concern that parts of far northeast Oklahoma and northwest Arkansas will struggle to climb above freezing before the onset of precipitation late Tuesday, leading to some potential for light freezing rain. The valleys of northwest Arkansas will liekly be most at risk for any light freezing rain.
WITH HIGHS REMAINING BELOW FREEZING ACROSS THE NORTH. HIGH PRESSURE WILL SETTLE OVER NORTHEAST ARKANSAS TONIGHT. ALLOWING TEMPERATURES TO REMAIN A LITTLE WARMER. AS THE HIGH SLOWLY MOVES EAST. WITH WARM FRONT LIFTING NORTH. CURRENT THINKING IS THAT WARM FRONT WILL TRAP COLDER AIR ACROSS THE NORTHERN COUNTIES. WITH FREEZING RAIN POSSIBLE TUESDAY NIGHT ACROSS THE NORTHERN TWO ROWS OF COUNTIES. THIS IS NOT A GREAT SETUP FOR WIDESPREAD/IMPACTFUL FREEZING RAIN.

An Arctic high pressure center was moving directly over the state of Missouri this morning, causing temperatures to fall well into the single digits. For tonight, south winds will return as high pressure shifts to the east. An increase in cloud cover will also facilitate warmer conditions with lows only falling into the 20s in southwest Missouri. This feature will approach the Ozarks Region by Tuesday, forcing a quick round of rain, snow, sleet, and freezing rain. Therefore, mostly snow and sleet are expected along and north of the Highway 54 corridor. We think the freezing rain amounts will be limited to just a glaze or a few hundredths of an inch.
AREAS OF LIGHT SNOW AND PATCHY FREEZING RAIN HAVE BEEN REPORTED AND WILL CONTINUE AS THE IMPULSE TRACKS TO THE EAST. DRIER AIR MOVES ACROSS THE AREA OVERNIGHT AS UPPER RIDGING DEVELOPS. SOME LIGHT FREEZING RAIN IS POSSIBLE THIS MORNING MAINLY OVER EASTERN PORTIONS OF THE REGION.
