309 AM PDT WED OCT 14 2015 GRADUALLY COOLER THROUGH THE UPCOMING WEEKEND AS ONSHORE FLOW STRENGTHENS AND CLOUDS INCREASE AHEAD OF A WEAK LOW PRESSURE SYSTEM OFF THE COAST.
A passing cold front will clear our southeast Big Bend counties by midday with clear skies and pleasant conditions in its wake. High temperatures will range from the lower 80s across southeast Alabama to the mid/upper 80s across the Suwannee Valley in Florida.
230 AM EDT WED OCT 14 2015 A COLD FRONT WILL MOVE THROUGH THE AREA EARLY THIS MORNING FOLLOWED BY HIGH PRESSURE THROUGH LATE WEEK.
215 AM PDT WED OCT 14 2015 An upper level ridge will begin to strengthen over the next several days bringing a return to warm and dry weather. The ridge is expected to shift east of the area by the weekend which will bring increased cloud cover, cooler temperatures, and a chance of rain. Satellite reveals a westerly flow regime over the forecast area which according to all the latest model data will become a strengthening ridge through the next 36 to 48 hours. Winds will take a northerly bias today as high pressure builds over southern Canada and shift to the northeast tonight and Thursday becoming noticeably breezy down the Purcell trench and into the Columbia Basin.
On Thursday, however, south to southwesterly winds will increase through the day with the approach of a strong cold front, and as a result, conditions will be in reasonable proximity to Red Flag criteria across far southeast Oklahoma, where fuels are driest per Oklahoma forestry.

TODAY THROUGH THURSDAY COMBINATION OF WEAK UPR LEVEL RIDGING ACROSS DESERT SW AND LOW LEVEL HIGH CENTER ACROSS THE LOW MS RIVER VALLEY WILL PRODUCE DRY CONDITIONS WITH SOMEWHAT MODEST SRLY FLOW TODAY BY PANHANDLE STANDARDS. THIS COMBINATION WILL IN TURN LEAD TO RELATIVELY LARGE DIURNAL RANGES RUNNING 30 TO 35 DEG THE NEXT FEW DAYS AS HIGHS REACH THE LOWER 90S IN SE HALF OF THE TX PANHANDLE. A SHORT WAVE WILL RE-ENFORCE AN EXISTING LARGE SCALE TROUGH ACROSS THE ERN US. THIS SYSTEM WILL ALSO DRIVE THE NEXT COLD FRONT INTO THE PANHANDLES BY THU AFTN. THURSDAY NIGHT THROUGH WEDNESDAY GUSTY NORTHEASTERLY UPSLOPE SURFACE FLOW BEHIND THE COLD FRONT THURSDAY NIGHT AS COLD AIR ADVECTION CONTINUES ACROSS THE FORECAST AREA.
COLD FRONT HAS FINALLY PUSHED TO THE SOUTH OF PIKE AND BARBOUR COUNTIES THIS MORNING BASED ON SURFACE ANALYSIS. HAVE ADJUSTED HIGHS A COUPLE OF DEGREES WARMER TO ACCOUNT FOR THE MOSTLY DRY CONDITIONS AT THE SURFACE AND DRY DEWPOINTS. DEWPOINTS ARE EXPECTED TO MIX DOWN AT LEAST INTO THE LOWER 40S THIS AFTERNOON.

THIS CAUSES THE STRONG UPPER RIDGE ANCHORED OVER THE GREAT BASIN THE SEVERAL DAYS TO BEGIN ITS EASTWARD SHIFT TOWARDS THE CENTRAL ROCKIES. HEIGHT FALLS/STG PRES RISES BENEATH THE JET APPEAR TO DRIVE A WEAK COLD FRONT SOUTHWESTWARD INTO NORTHEAST COLORADO BY EARLY ON THURSDAY. BUT NOT AS MUCH IN THE HIGH COUNTRY.
After a clear/chilly night tonight with lows dipping into the lower to middle 40s, high pressure will shift east of the region and southwesterly winds will bring much warmer conditions back into the area on Thursday.
