NWS Jackson, MS wrote its last area forecast discussion before the first event at May 12, 9:19 AM CST, 4 hours 49 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1019 AM CDT THU MAY 12 2016 .UPDATE...Isolated showers were occurring late this morning across northern portions of the cwa...with dry conditions elsewhere. Chances for showers/storms will slowly increase today as a cold front moves into the region. Highs this afternoon will climb into the low to mid 80s. As for the current fcst...adjusted pops for today across the cwa to slow development of shwrs/strms based on latest radar trends and model guidance. Shear does not look favorable for severe storms today...but a strong storm cannot be ruled out. Also adjusted the hourly temps and dewpts based on the latest trends. /27/ && .AVIATION...AN ABUNDANCE OF BOUNDARY LAYER MOISTURE WILL YIELD REDEVELOPING STRATOCUMULUS ACROSS THE AREA...INITIALLY THESE WILL BE MOSTLY IN THE MVFR RANGE BUT THEY SHOULD MIX UP TO VFR CATEGORY AS WE GO INTO THE AFTERNOON. EXPECT INCREASING CHANCES FOR TSRA AHEAD OF A COLD FRONT MAINLY OVER THE GLH/GWO/GTR CORRIDOR THROUGH LATE AFTN EVENTUALLY SHIFTING SOUTH AS WE GO INTO THE EVENING. WILL BE MONITORING FOR IFR/LIFR STRATUS DEVELOPMENT LATE TONIGHT INTO THE EARLY MORNING HOURS BEFORE MUCH DRIER AIR CAN MOVE IN BEHIND THE FRONT. /EC/ && .PREV DISCUSSION... /issued 435 AM CDT THU MAY 12 2016/ SHORT TERM...TODAY THROUGH FRIDAY NIGHT...AN UPPER TROUGH WILL DRAG A COLD FRONT INTO THE DELTA THIS AFTERNOON AND THE BOUNDARY WILL MOVE ACROSS THE AREA DURING THE EVENING HOURS. MOISTURE WILL INCREASE OUT AHEAD OF THE BOUNDARY WITH PWATS CLIMBING ABOVE 1.5 INCHES AND DEWPOINTS IN THE UPPER 60S. SHOWERS AND THUNDERSTORMS WILL DEVELOP WITH THE BULK OF THE ACTIVITY NORTH OF THE I-20 CORRIDOR. THE GFS INDICATES LAPSE RATES OF 6.5-6.8 C/KM ALONG WITH ABOUT 20-25KTS OF DEEP LAYER SHEAR. HI-RES MODELS DO NOT LOOK TO IMPRESSIVE LATER THIS AFTERNOON AND EVENING WITH THE CONVECTION...BUT AN ISOLATED STRONG TO POSSIBLY SEVERE STORM CANNOT BE RULED OUT. THE COLD FRONT WILL EXTEND ACROSS THE SOUTHERN PORTIONS OF THE AREA BY MIDNIGHT, BUT THE GLOBAL MODELS SUGGEST THE SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO THE EARLY OVERNIGHT HOURS BEFORE DISSIPATING BY EARLY MORNING. SURFACE HIGH PRESSURE RIDGING WILL BUILD INTO THE AREA ON FRIDAY AND WITH COOLER NORTHERLY FLOW TEMPERATURES WILL RANGE FROM AROUND 80 IN THE NORTH TO THE MID 80S IN THE SOUTH. OVERNIGHT LOWS FRIDAY NIGHT WILL FALL INTO THE MID/UPPER 50S ACROSS THE AREA. /15/ LONG TERM...Saturday through Wednesday...come Saturday morning a stalled cold front will be draped along the Gulf coast while a second cold front will be nearing northern Mississippi. This second cold front still looks to drop into our cwa during the afternoon as a dry cold front Saturday but there are a couple of models suggesting convection over our southwest along the front. Wl go with consensus and not introduce pops. This cold front will stall as well Saturday evening just south of our cwa. In its wake a surface High over the central CONUS will track east through Sunday to the mid Atlantic seaboard by Monday morning. This will keep the Gulf closed and limit low level moisture through the weekend maintaining a dry air mass over the eastern portions of our cwa but rain chances will be hard to ignore over the western portions of our cwa as we go into Sunday. Our flow aloft will become near zonal Sunday and then back to the southwest Monday ahead of a deepening trough over the southwest CONUS. Convective activity over the southern plains will try to spread east into our cwa as early as Saturday night and continue through Sunday night. Return flow will develop back over our cwa during the day Monday which will help send the stalled front back north as a weak warm front. The increase in deep moisture combined with daytime heating will contribute to a greater coverage of afternoon and evening storms over our cwa. Most of the convection should see a distinct diurnal weakening with the loss of daytime heating but the ECMWF is showing a potent shortwave in the southwest flow aloft Monday night that could prolong rain chances into Tuesday. There are significant differences between the GFS and ECMWF with timing and rainfall amounts across our CWA Tuesday night into Thursday but a wet period where several inches of rain will be possible over the area looks likely. /22/ && .PRELIMINARY POINT TEMPS/POPS...
