Area forecast discussion, Aug 6, 3:24 PM CDT, 5 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 324 PM CDT SAT AUG 6 2005 .SHORT TERM...(TONIGHT THROUGH TUESDAY) MAIN FEATURE OF CONCERN THROUGH THE SHORT TERM WILL BE THE STAGNANT UPPER LEVEL LOW. FROM THIS FEATURE...ALL THE FORECAST ISSUES EMANATE. RAIN CHANCES...LOWS AND HIGHS WILL ALL BE IMPACTED. OVERALL...MODELS AND GUIDANCE ARE WITHIN A FEW DEGREES OF EACH OTHER...WITH THE MOST SIGNIFICANT DIFFERENCES IN POPS. NOT GOING TO BUY INTO LOWER POPS WHICH THE NAM IS LEANING TOWARDS OVER OUR NORTHWESTERN COUNTIES. ALTHOUGH THAT AREA IS LESS INFLUENCED BY THE LOW/REMNANT TROUGH...SUFFICIENT LOW LEVEL INSTABILITY SHOULD BE MORE THAN ENOUGH TO BRING ABOVE NORMAL POPS TO THE AREA. CLOSER TO THE LOW...GUIDANCE POPS ARE MORE IN LINE...AND THE MAIN BONE OF CONTENTION WILL BE TEMPERATURES. STAYED SOMEWHAT CONSERVATIVE THROUGH THE PERIOD...DIFFERENCES IN CLOUD COVER/SHOWER COVERAGE WILL MAKE BIG DIFFERENCES ON THE SMALL SCALE VARIATION OF TEMPS. ALL IN ALL...GOOD CONFIDENCE IN THE GENERAL FORECAST OF THE LOW AND LINGERING TROUGH...AND ABOVE NORMAL POPS. CONFIDENCE IS ONLY SLIGHTLY LOWER ON TEMPERATURES. .LONG TERM...(WEDNESDAY THROUGH SATURDAY) NO MAJOR CHANGES PLANNED TO THE LONG TERM PORTION OF THE FORECAST AT THIS POINT. IN SPITE OF SUBTLE SHUFFLING OF UPPER LEVEL FEATURES...THE MAIN FLAVOR OF THE FORECAST REMAINS UNCHANGED...WITH NEAR NORMAL TEMPERATURES AND ABOVE NORMAL POPS. A STRONG TROUGH APPROACHING THE PACIFIC COAST NUDGES THE WESTERN CELL OF THE UPPER RIDGE EASTWARD...WHICH ESSENTIALLY MERGES WITH THE EASTERN/BERMUDA HIGH CELL. IN SPITE OF A WEAK UPPER LEVEL RIDGE BUILDING OVER THE AREA LATE IN THE WEEK AND INTO THE WEEKEND...ENOUGH MOISTURE REMAINS...AND SOUTHERLY SURFACE FLOW SHOULD SUSTAIN NORMAL TO SLIGHTLY ABOVE NORMAL POPS. SUSPECT MEX TEMPS MAY BE A DEGREE OR TWO HIGH IN LIGHT OF THE ABOVE NORMAL POPS AND MOISTURE...BUT SEE NO PROBLEM WITH THE CURRENT FORECAST HIGHS AND LOWS. TWEAKS WILL BE MINOR...IF ANY. && .PRELIMINARY POINT TEMPS/POPS...
