DISCUSSION
AS OF 210 AM EDT WEDNESDAY...
KEY MESSAGE 1: ANOTHER PLEASANT DAY IS EXPECTED ACROSS THE REGION TODAY
AS HIGH PRESSURE CONTINUES TO BRING A PERIOD OF DRIER WEATHER. HIGH
TEMPERATURES WILL BE A FEW DEGREES WARMER TODAY UNDER LIGHT
SOUTHERLY FLOW WITH DAYTIME HIGHS CLIMBING INTO THE 80S AREAWIDE.
HEADING INTO THE LATTER HALF OF THE WEEK, WARM AND UNSETTLED WEATHER
IS EXPECTED AS THE REGION REMAINS SANDWICHED BETWEEN HIGH PRESSURE
TO THE SOUTH AND AN UPPER LEVEL TROUGH TO THE NORTH, WITH ZONAL FLOW
BRINGING SEVERAL DIFFERENT DISTURBANCES TO THE REGION. WITH BROAD
SOUTHWESTERLY FLOW USHERING IN PLENTY OF MOISTURE, CHANCES FOR
SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE. WHILE THERE DOESN'T LOOK
TO BE ANY REAL DEFINED BOUNDARY TO HELP DRIVE SHOWER ACTIVITY, THE
SHORTWAVE ACTIVITY THURSDAY AND FRIDAY MAY PROVIDE ENOUGH ENERGY TO
DRIVE AFTERNOON SHOWER AND THUNDERSTORM CHANCES. IF INGREDIENTS
ALIGN, THERE COULD BE THE POTENTIAL FOR SOME STRONGER THUNDERSTORMS
BOTH AFTERNOONS, BUT GENERALLY MORE GARDEN-VARIETY THUNDERSTORMS CAN
BE EXPECTED. SHOWER ACTIVITY IS EXPECTED TO WANE TOWARDS THE
EVENINGS WITH LOSS OF DIURNAL HEATING. HIGH TEMPERATURES THURSDAY
WILL RISE INTO THE MID TO UPPER 80S WITH DEWPOINTS AROUND 70
DEGREES, RESULTING IN HEAT INDICES IN THE UPPER 80S TO AROUND 90.
KEY MESSAGE 2: A BERMUDA HIGH WILL BE REMAIN IN PLACE SUNDAY THROUGH
TUESDAY, WHICH WILL KEEP WARM, MOIST FLOW PROGRESSING INTO THE
REGION WHILE VARIOUS SYSTEMS TRAVEL WEST-TO-EAST IN QUICK ZONAL FLOW
ALOFT. A MORE APPRECIABLE TROUGH WILL DRIVE SOUTHEASTWARDS ON
TUESDAY, AND THAT WILL BREAK DOWN THE BERMUDA HIGH AND SHUNT THE
PLUME OF MOISTURE SOUTH AND EAST OF OUR REGION. SOME FORECAST
GUIDANCE STILL SUGGESTS THERE'S A POCKET OF DRY AIR IN THERE
SOMEWHERE BETWEEN SYSTEMS ON SUNDAY, BUT THE TIMING OF THIS STILL
REMAINS A LITTLE UNCERTAIN. ANY POTENTIAL FOR STRONGER STORMS WILL
DEPEND ON THE TIME OF DAY THAT THESE PERIODIC 700MB TROUGHS PUSH
EAST. IF THEY ARE TIMED DURING PEAK HEATING, THE WARM, MOIST
ENVIRONMENT AND GRADUALLY INCREASING SHEAR SUGGESTS THE INGREDIENTS
COULD BRIEFLY MATERIALIZE. SOME OF THE EXPERIMENTAL MACHINE LEARNING
ENSEMBLES HAVE SOME LOW END PROBABILITIES, BUT A GREATER FOCUS
SOUTH. SO WILL KEEP AN EYE OUT, BUT ANY POTENTIAL FOR STRONGER
STORMS WILL BE CONTINGENT ON THE TIMING OF SYNOPTIC FORCING. AFTER
TUESDAY, WE'LL BE UNDER THE INFLUENCE OF A BROAD UPPER LOW, BRINGING
TEMPERATURES NEAR TO JUST BELOW NORMAL. HOWEVER, THERE'S STILL
SEVERAL EMBEDDED SYSTEMS. SO SHOWERS COULD REMAIN IN THE FORECAST
MID TO LATE NEXT WEEK, BUT THUNDERSTORM CHANCES WILL MINIMIZE.
