DISCUSSION
(TODAY THROUGH SATURDAY)
ISSUED AT 1226 AM CDT SUN JUN 28 2026
LATEST WATER VAPOR IMAGERY AND UPPER AIR ANALYSIS SHOW AN UPPER
LEVEL RIDGE CENTERED OVER THE REGION WITH DRY SUBSIDENT AIR. THIS
SYSTEM WILL MAINTAIN CONTROL OVER THE FORECAST AREA ON SUNDAY
KEEPING ANY SIGNIFICANT SHOWER ACTIVITY OUT OF THE FORECAST. PRETTY
TYPICAL SUMMERTIME TEMPERATURES AND HUMIDITY IS EXPECTED WITH HIGHS
IN THE LOW TO MID 90S AND THE MAX AFTERNOON HEAT INDEX RANGING FROM
100 TO 107 DEGREES. THIS IS BELOW LOCAL HEAT ADVISORY CRITERIA, WITH
A MODERATE HEAT RISK, WHICH MEANS AFFECTS MAY OCCUR TO THOSE WHO ARE
SENSITIVE TO HEAT, ESPECIALLY THOSE WITHOUT COOLING AND HYDRATION.
BY MONDAY INTO TUESDAY, THE CENTER OF THE UPPER LEVEL RIDGE WILL
BEGIN TO MOVE TO THE NORTH AND NORTHEAST. THERE SHOULD BE ENOUGH
SUBSIDENCE AND DRY AIR TO SUPPRESS ANY SIGNIFICANT SHOWER ACTIVITY
WITH THE TYPICAL HEAT AND HUMIDITY CONTINUING. THE FLOW AROUND THE
UPPER HIGH WILL BRING A MODEST SAHARAN AIR LAYER INTO THE REGION
WITH A PLUME OF DUST MOVING OVERHEAD. THIS WILL MAKE FOR HAZY
DAYTIME SKIES, BUT SUNRISES AND SUNSETS SHOULD BE COLORFUL. THE
PARTICLES MAY REACH MODERATE LEVELS WHICH MEANS IT MAY HAVE AFFECTS
TO THOSE WHO ARE UNUSUALLY SENSITIVE TO AIR POLLUTION.
BY MID WEEK, THE UPPER LEVEL RIDGE IS EXPECTED TO BE NORTHEAST OF
THE REGION AND OVER THE MID-ATLANTIC STATES. THIS WILL ALLOW FOR A
WEAKNESS TO DEVELOP ALOFT WITH A WEAK UPPER LEVEL LOW OR INVERTED
TROUGH AXIS MOVING IN. THIS WILL ALLOW MAINLY DIURNAL SHOWERS AND/OR
THUNDERSTORMS TO DEVELOP DURING MAX HEATING ALONG WITH ANY SEA
BREEZE AND MESOSCALE BOUNDARIES. ANY CONVECTION THAT DEVELOPS IS
EXPECTED TO DIMINISH AFTER SUNSET.
NOT MUCH CHANGE IN TEMPERATURES OR HUMIDITY IS EXPECTED DURING THE
MID TO LATTER PART OF THE WEEK.
