THANKFULLY AN APPROACHING RIDGE AND ASSOCIATED SOUTHWEST FLOW IN THE MID LEVELS WILL BRING WAA BY FRIDAY.
306 PM CST Thu Feb 5 2015 The center of the retreating arctic high pressure was well to the east by this afternoon allowing return flow to develop over Kansas. For example, 850 mb temperature at KMHK goes from -3 C at 18UTC today to 16 C 24 hours later! Lows tonight will be considerably warmer than this morning and the temperatures shouldn't fall much after 06Z given the magnitude of the warm advection. For Friday, expect building heights with the 500 mb ridge centered over the Rockies. Downslope air with a lee trough in the high plains and southwest flow across Kansas. With very warm air, expect highs to be much warmer, especially over the southwest counties of the forecast area.
306 PM CST THU FEB 5 2015 SHORT TERM MODELS LOOK IN GOOD AGREEMENT WITH A WARM OVERRUNNING FREEZING RAIN EVENT TONIGHT ACROSS NORTHWEST NORTH DAKOTA WITH THERMAL PROFILES COLD ENOUGH FOR SNOW ACROSS THE NORTH CENTRAL FURTHER DOWN STREAM.

High pressure was directly over the state of Missouri, and will translate east this evening.
HIGH PRESSURE WAS CENTERED OVER CENTRAL IL WHILE A WARM FRONT WAS MAKING ITS WAY ACROSS MN. NORTHWEST FLOW ALOFT WILL DRIVE ANOTHER WEAK MID-LEVEL WAVE SOUTHEAST TOWARD THE AREA AS A WARM FRONT PUSHES NORTHEASTWARD OUT OF THE PLAINS. INCREASING WAA/ISENTROPIC LIFT AHEAD OF THE MID-LEVEL WAVE AND SURFACE WARM FRONT WILL AID IN SATURATING 700-500MB LATER FOR INCREASING ALTOCUMULUS CLOUD OVERNIGHT. ALSO REMOVED MENTION OF FREEZING DRIZZLE AS WELL AS ANY LOWER LEVEL STRATUS THAT MAY FORM WILL NOT BE DEEP ENOUGH FOR COLLISION/COALESCENCE PROCESS. WARM FRONT THEN SETS UP NORTHWEST TO SOUTHEAST ACROSS SOUTHERN MN/NORTHERN IA FRIDAY NIGHT AS ANOTHER WEAK MID-LEVEL WAVE MOVES ACROSS NORTHERN MN/WI. WILL HAVE TO WATCH FOR THE POSSIBILITY OF SOME LIGHT PATCHY FREEZING DRIZZLE ACROSS THAT AREA AS SOUNDINGS SHOW THICKENING STRATUS AND A LACK OF CLOUD ICE.
THE COLD FRONT WILL MOVE INTO NORTHERN MN AND SLOW DOWN OVERNIGHT LEAVING MUCH OF THE AREA IN A COL PATTERN. NO LONGER ARE INDICATING FREEZING DRIZZLE OR FREEZING RAIN AND HAVE REMOVED AND NAM IS TOSSED OUT. NAM/ECMWF/GFS/SREF ALL AGREE ON THE GENERAL TRACK OF THE LOW.
A COLD FRONT THAT MOVED THROUGH S TX EARLIER THIS MORNING HAS RESULTED IN COOLER TEMPS AND MOD N WINDS ACROSS THE BAYS AND NEARSHORE AND OCCASIONALLY STRONG N WINDS ACROSS THE OFFSHORE COASTAL WATERS. TONIGHT'S LOWS ARE FCST TO BE APPROX 10 DEGREES COOLER THAN LAST NIGHT. THE SLY FLOW WILL USHER LOW LEVEL MOISTURE AND WARMER TEMPS BACK INTO S TX.

Winds will remain light/variable through the morning, then will gradually become southerly this afternoon as the high settles into the Ohio River Valley. Arctic high pressure is settling over central Illinois from the northwest this morning with temperatures ranging from -8 in Lacon to 19 at Mount Carmel Airport. As the center of the high approaches and crosses the state, winds will decrease through the morning eventually becoming light southerly by afternoon. High pressure builds back into the Midwest as an upper trof sets up more northwesterly flow aloft. Southerly winds with warmer temps up over a melting snowpack and enhanced llvl RH setting up for a patchy advection fog threat. That being said, cloud cover may also interfere with the extent of the diurnal swing and raise the lows a bit. Have left the wording with freezing fog for now.
HIGH PRESSURE (1036 MB) WAS CENTERED OVER STL AT 18Z WITH A CONTINUED N-NELY COLD ADVECTIVE FLOW INTO THE TN VALLEY.

SHORT TERM GUIDANCE SUGGESTS THIS CIRRUS WILL CONTINUE TO SWEEP NORTH AND WEST TODAY COINCIDENT WITH TRACK OF THE MID LEVEL RIDGE AXIS.
AT H5 RIDGE TO THE WEST AND TROUGH TO THE EAST. UPPER LEVEL HIGH PRESSURE WILL CONTINUE TO BUILD EAST INTO THE REGION TONIGHT AND FRIDAY. HIGHS WILL BE COOLER IN THESE LOCATIONS. MAINLY IN THE LOWER TO MID 50S.
351 PM CST THU FEB 5 2015 HIGH PRESSURE WILL CONTINUE TO PUSH EAST TONIGHT AND KEEP THE FORECAST AREA IN THE WAA REGIME THROUGH FRIDAY. LEANED TOWARDS THE GFS FOR MINIMUM TEMPS TONIGHT AS THE NAM/ECMWF/SREF SEEMED TOO COLD WITH THE HIGH CLOUDS STREAMING IN OVERNIGHT. AND SUBSEQUENTLY WARMER WITH SEVERAL DAYS OF ABOVE NORMAL TEMPS AND SOME MINOR MELTING. WHICH ARE 15-20 DEGREES WARMER THAN THE NAM MOS INTO SAT. RAW MODEL TEMP CONSENSUS IS SOMEWHAT WARMER THAN NAM MOS. WILL LEAN TOWARD THE COOLER END OF FOR MINS AS WELL. THE QUESTIONS BECOME HOW MUCH WILL REACH THE GROUND WITH DRY AIR BELOW 3KM SO NOTHING OF SIGNIFICANCE IS ANTICIPATED EVEN THOUGH SURFACE TEMPS WOULD SUGGEST LIGHT FREEZING RAIN.

HAVE EXTENDED THE MENTION OF DRIZZLE OR FREEZING DRIZZLE THROUGH 11 AM FOR THE METROPLEX EAST THROUGH TERRELL AND SOUTH TO NEAR ATHENS. COLD TODAY FOLLOWED BY A SUNNY AND MUCH WARMER WEEKEND. SURFACE OBSERVATIONS ON THE NORTH SIDE OF THE DFW METROPLEX SUGGEST THAT LOW LEVEL DRYING IS BRINGING AN END TO THE DRIZZLE JUST BEFORE TEMPERATURES GET DOWN TO FREEZING. A BRIEF PERIOD OF FREEZING DRIZZLE WILL BE POSSIBLE IN NORTHERN AREAS. THE RELATIVELY WARM GROUND TEMPERATURES AND SHORT DURATION OF FREEZING DRIZZLE SUGGEST THAT NO SIGNIFICANT IMPACTS WILL OCCUR THIS MORNING.
1008 AM CST THU FEB 5 2015 SKIES ARE SUNNY ACROSS THE ENTIRE FORECAST AREA THIS MORNING WITH TEMPERATURES RANGING FROM THE LOWER 20S TO LOWER 30S. TEMPERATURES HAVE BEEN DROPPING RAPIDLY BEHIND THE FRONT AS THE DENSE ARCTIC AIRMASS SINKS SOUTH WITH TEMPERATURES ALREADY IN THE LOW TO MID 20S IN NORTHEAST AR/MO BOOTHEEL/NORTH TN.
