NWS Huntsville, AL wrote its last area forecast discussion before the first event at May 26, 2:29 PM CST, 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 329 PM CDT MON MAY 26 2014 .DISCUSSION... A SUMMER-LIKE PATTERN WILL CONTINUE TO HOLD SWAY OVER THE REGION FOR THE FORECAST PERIOD. CHANCES FOR SHOWERS/TSTMS WILL INCREASE OVER THE NEXT FEW DAYS AS THE REMNANTS OF AN UPR LOW COMBINE WITH SUFFICIENT DAYTIME HEATING AND RESULTING INSTABILITY. CHANCES FOR PRECIP WERE INCREASED A LITTLE IN THE EARLY PORTION OF THE FORECAST TO REFLECT INCREASED CONFIDENCE IN CONVECTION. OTHER CHANGES WERE GENERALLY MODEST. DETAILS FOLLOW BELOW. EARLY AFTERNOON ANALYSIS SHOWED A BROAD RIDGE STRETCHING ACROSS A GOOD PORTION OF THE CONUS, WHILE A VIGOROUS CLOSED UPR LOW CONTINUED TO SPIN SLOWLY EWRD ACROSS THE SOUTHERN PLAINS. THE POLAR JET WAS CONFINED WELL TO THE NORTH, GENERALLY ALONG AND NEAR THE US/CANADIAN BORDER AND WAS PROVIDING LITTLE SUPPORT FOR THE EWRD MOVEMENT OF THE UPR LOW. NEVERTHELESS, THIS FEATURE WILL FACTOR INTO OUR SENSIBLE WEATHER OVER THE NEXT SEVERAL DAYS. A RIDGE AXIS AHEAD OF THE UPR LOW STRETCHED FROM S-N ACROSS THE GULF COAST INTO THE CENTRAL PARTS OF THE TN/OH VALLEY. TEMPS AROUND THE AREA WERE RELATIVELY WARM WITH MOST VALUES IN THE MID 80S. A SMALL AXIS OF SHOWERS WITH AN ISOLD STORM OR TWO WAS PRESENT IN NW AL, FROM NEAR RUSSELLVILLE TO LEXINGTON. SHOWERS/TSTMS WILL DECREASE IN COVERAGE WITH THE LOSS OF DAYTIME HEATING DURING THE LATE AFTERNOON AND EVENING. A 20 POP WAS CARRIED OVER FOR THE EVENING HOURS ACROSS THE AREA. LOCATIONS NEAR/ADJACENT TO ONGOING CONVECTION MAY BE FAVORED FOR SOME LINGERING DEVELOPMENT THIS EVENING DUE TO SFC CONVERGENCE ALONG OUTFLOW BOUNDARIES. WITH THAT SAID, PATCHY FOG WAS INCLUDED FOR THE OVERNIGHT FORECAST FOR LAKE LOCATIONS AND WHERE RAIN HAS FALLEN SO FAR TODAY (IN NWRN AL AND IN DEKALB/MARSHALL COUNTIES). AN UPR TROUGH WILL BEGIN TO DIG OVER THE NW CONUS ON TUESDAY WITH PRONOUNCED DOWNSTREAM RIDGING DEVELOPING OVER THE SOUTHWEST CONUS INTO THE CENTRAL/NORTHERN PLAINS. EVENTUALLY, THE RIDGE WILL BUILD INTO THE NORTHERN PLAINS EFFECTIVELY CUTTING OFF THE SOUTHERN PLAINS LOW FROM THE POLAR WESTERLIES. MODEL CONSENSUS PAINTS A LIKELY SCENARIO...THE UPR LOW WILL LIKELY SETTLE SOMEWHERE OVER THE SOUTHERN MISS VALLEY AND GRADUALLY WEAKEN AS THE COLD AIR THAT DEFINES IT BECOMES INCREASINGLY DIFFUSE/MIXED. NEVERTHELESS, IN THE PROCESS, A LOBE OF VORTICITY ON THE EASTERN FLANK OF THE UPR LOW IS EXPECTED TO BEGIN TO PIVOT ACROSS THE TN VALLEY REGION TOMORROW. THIS WILL PROVIDE A BETTER FOCUS FOR SHOWER/TSTORM DEVELOPMENT. SO...POPS WERE INCREASED FOR TUESDAY INTO CHANCE CATEGORY. THIS ALIGNS WELL WITH MOS GUIDANCE FOR THE AREA AS WELL. PROVIDED THAT ADVECTING CIRRUS DOES NOT INHIBIT AMPLE HEATING...RESULTING MLCAPE VALUES ARE FORECAST TO REACH AROUND 1 KJ/KG TOMORROW AFTERNOON SUPPORTING MODEST CONVECTION. SHEAR IS WEAK...SO STRONG STORM ORGANIZATION REMAINS UNLIKELY. THE UPR VORTICITY PATTERN FOR WED/THURS BECOMES MUCH MORE DIFFUSE AND CHAOTIC AS THE UPR LOW TO OUR SW WANES IN STRENGTH/SIZE. FORCING FOR ASCENT OVERALL WILL THUS BE RELATIVELY WEAK...BUT THE PROSPECT FOR STRONG DAYTIME HEATING AND THE PRESENCE OF MULTIPLE LINGERING OUTFLOW BOUNDARIES SUGGESTS CHANCE POPS ARE NECESSARY FOR THE PERIOD. SHEAR AND STEERING FLOW WILL BE VERY WEAK THROUGH THE PERIOD. IN FACT...WINDS UP THROUGH THE ENTIRE TROPOSPHERIC COLUMN MAY BE LESS THAN 10 KTS FOR WED/THURS. GIVEN PW VALUES ~1.6 INCHES AND CAPES AROUND 1-1.5 KJ/KG...CELLS MAY PRODUCE LOCALLY HEAVY RAIN...BUT WILL BE VERY SLOW MOVING TO NEARLY STATIONARY. AS A RESULT...WE MENTIONED LOCALLY HEAVY RAINFALL POTENTIAL IN THE HWO UPDATE THIS AFTERNOON. THE UPR RIDGE OVER THE NORTHERN PLAINS WILL SLOWLY BUILD TO THE SOUTHEAST OVER THE OH/TN VALLEY BY NEXT WEEKEND. DEEP N-NE FLOW WILL DEVELOP PERHAPS AS EARLY AS FRIDAY AS THE RIDGE BUILDS TO OUR NORTH. A LOW-LVL CONFLUENCE BOUNDARY WILL CROSS INTO THE AREA AND MAY PROVIDE FOCUS FOR LIFT ON FRIDAY. THUS...CHANCE POPS WERE RETAINED. IT IS UNCLEAR YET IF THE BOUNDARY WILL ENTIRELY PASS TO OUR SW OR REMAIN STALLED IN THE AREA. SO...CHANCE POPS WERE ALSO RETAINED FOR SATURDAY. KDW && .AVIATION... /ISSUED 1230 PM CDT MON MAY 26 2014/ FOR 18Z TAFS...EVEN WITH SCT/BKN MID/HIGH CLOUDS IN PLACE ACROSS MUCH OF THE AREA...VFR CONDS ARE XPCTED TO PREVAIL WELL INTO THE EVENING HRS. ISO SHRA/TSRA REMAIN POSSIBLE INTO THE EARLY EVENING PERIOD AS WELL...ALTHOUGH WITH THE COVERAGE/PROB XPCTED TO BE FAIRLY LOW...WILL MAINLY USE AMD/UPDATES IF NEEDED IN THE TAFS THIS AFTERNOON. THERE MAY BE A SLIGHTLY BETTER CHANCE OF PRECIP ON TUE...AS UPPER WAVES WORK THEIR WAY INTO THE REGION FROM THE W.
