LITTLE CHANGE WITH THIS MORNING'S FORECAST UPDATE. WATER VAPOR
IMAGERY THIS MORNING REVEALS AN UPPER TROUGH ACROSS THE NORTHEAST US
AND ANOTHER HEADING TOWARDS THE WEST COAST. UPPER RIDGING CAN BE
SEEN BUILDING ACROSS THE FOUR CORNERS REGION, LEAVING US WITH
QUASI-ZONAL FLOW ALOFT OVER THE SOUTHEAST. UPPER LEVEL RIDING
WILL GRADUALLY EXPAND EAST THROUGH THE WEEK. SURFACE HIGH PRESSURE
ACROSS THE SOUTHEAST AND AN INFLUX OF DRY AIR (0.59" PWAT ON THE
12Z KBMX SOUNDING) WILL KEEP A DRY FORECAST IN PLACE THROUGH THE
WEEKEND. WE WILL NEED TO MONITOR FOR SOME PATCHY FOG DEVELOPMENT
EARLY THURSDAY MORNING. FORECAST SOUNDINGS SUGGEST ENOUGH
LINGERING LOW LEVEL MOISTURE IS IN PLACE TO PRODUCE SOME PATCHY
FOG AS WINDS BECOME LIGHT. LATEST HREF GUIDANCE INDICATES A 30-50%
CHANCE FOR VIS LESS THAN A MILE. INCREASING PROBABILITIES AND RAP
GUIDANCE PROMOTING CONDENSATION PRESSURE DEFICITS FROM 2-4MB
PROVIDE ENOUGH CONFIDENCE TO INTRODUCE PATCHY FOG ACROSS OUR
NORTHWESTERN COUNTIES. OTHERWISE, OUR WARMING TREND WILL CONTINUE
WITH HIGH TEMPS REBOUNDING BACK INTO THE MID TO UPPER 70S BY THE
WEEKEND. LOWS WILL GENERALLY BE IN THE 40S AND 50S.
OUR PATTERN BEGINS TO CHANGE LATE THIS WEEKEND INTO EARLY NEXT
WEEK AS A STOUT UPPER TROUGH SLIDES ACROSS THE GREAT LAKES REGION
WHILE SENDING A COLD FRONT OUR WAY. WE WILL SEE PWATS ON THE RISE
AHEAD OF THIS BOUNDARY WHICH WILL HELP PROMOTE A 20-40% CHANCE OF
SHOWERS AND THUNDERSTORMS. WE HANG ONTO LOW TO MODERATE RAIN
CHANCES THROUGH MID WEEK AS A SERIES OF SHORTWAVES PASS NEARBY.

THE ONLY ASIDE TO VFR CONDITIONS OVER THE NEXT 24 HOURS IS THE
POTENTIAL FOR PATCHY EARLY-MORNING MVFR FOG TO AFFECT SOME
CENTRAL ALABAMA TERMINALS.

FIRE WEATHER
DRY CONDITIONS WITH CONTINUED DROUGHT WILL IMPACT THE AREA
THROUGH MUCH OF THE UPCOMING WEEKEND. WINDS WILL GUST AT TIMES
THIS AFTERNOON OUT OF THE WEST-NORTHWEST, GENERALLY FROM 15-20
MPH. WINDS WILL RELAX THIS EVENING AND REMAIN LIGHT THROUGH THE
REMAINDER OF THE WEEK. MIN RH VALUES WILL GENERALLY BE IN THE
40-50% RANGE TODAY AND TOMORROW. RHS FALL INTO THE 30-35% RANGE
ACROSS OUR SOUTHEASTERN AREAS ON FRIDAY. HOWEVER, OUR SIGNIFICANT
FIRE POTENTIAL REMAINS LOW. MIN RHS INCREASE BACK INTO THE 40-50%
RANGE FOR MOST OVER THE WEEKEND.
