251 PM MST THU JAN 21 2016 RIDGE BUILDS TOWARDS THE UT-CO STATE LINE BY MORNING. STRONG HIGH PRESSURE WILL PERSIST THROUGH FRIDAY NIGHT. THIS HIGH PRESSURE SYSTEM WILL CARRY PLENTY OF HIGH CLOUDS WITH IT.
TONIGHT THE H500 RIDGE MOVES EAST WITH INCREASING LOW LEVEL WARM ADVECTION SETTING UP AT H850 IN EASTERN MONTANA. WHILE THERE IS SOME UNCERTAINTY IF THE LOW LEVEL WARM ADVECTION ERODES THE INVERSION THERE MAY BE LIMITED POTENTIAL FOR FOG. WILL NOT HIT THIS TOO HARD BUT WILL ADD PATCHY FOG AGAIN TONIGHT SINCE THERE WILL BE POTENTIAL FOR WEAK UPSLOPE FLOW WEST ON THE BACK SIDE OF THE HIGH. THE WARM FRONT WILL BEGIN TO PUSH INTO WESTERN NORTH DAKOTA. AN UPPER LEVEL RIDGE WILL PUSH INTO THE AREA THIS WEEKEND.
Dry conditions will persist across western Kansas tonight and Friday as upper level ridging begins to break down as it moves eastward across the Central and Southern Rockies into the Western High Plains. For tonight, a prevailing northerly low level flow will help reinforce the colder air mass already settling into the high plains. This will begin to slowly erode the colder air mass across the high plains with the NAM/GFS showing H85 temperatures climbing a little above 0C by mid afternoon.
310 PM CST THU JAN 21 2016 WATER VAPOR SATELLITE IMAGERY SHOWS THE UPPER LEVEL LOW THAT BROUGHT SHOWERS AND THUNDERSTORMS TO NORTH AND CENTRAL TEXAS TODAY WAS LOCATED JUST EAST OF THE DFW AREA AS OF 20Z.

Dry conditions will persist across western Kansas tonight and Friday as upper level ridging begins to break down as it moves eastward across the Central and Southern Rockies into the Western High Plains. For tonight, a prevailing northerly low level flow will help reinforce the colder air mass already settling into the high plains. This will begin to slowly erode the colder air mass across the high plains with the NAM/GFS showing H85 temperatures climbing a little above 0C by mid afternoon. Precip chances will remain absent across western Kansas early in the period as short range models indicate upper level ridging slowly transitioning eastward across the Central Plains.
302 PM CST THU JAN 21 2016 Upper low over eastern Kansas this afternoon with water vapor showing additional waves over north Texas and the Dakotas. Weak isentropic ascent on modest warm air advection near the surface could yet support some light freezing drizzle into the early evening in southeastern areas but still appears this will be light if anything. Weak cold air advection takes hold overnight into Friday as high pressure builds in. This will allow for southerly flow and a lee side trough in the high plains.
