SCATTERED SHOWERS AND THUNDERSTORMS WERE ONGOING ACROSS PORTIONS
OF NRN AR THIS THURSDAY MORNING. THIS ACTIVITY IS ANTICIPATED TO
DROP SWRD THROUGH THE MORNING HOURS. BY MIDDAY, CONVECTION SHOULD
MOVE INTO SRN AR AHEAD OF A WEAK FRONTAL BOUNDARY. WHILE
ORGANIZED SEVERE WEATHER IS NOT EXPECTED, A FEW STORMS COULD
PRODUCE DAMAGING WINDS AND OR LARGE HAIL. DUE TO RAIN AND CLOUDS
IN THE FORECAST TODAY, HIGH TEMPERATURES ARE ONLY EXPECTED TO
RANGE FROM UPPER 80S TO LOWER 90S WITH HEAT INDEX VALUES BETWEEN
90 AND 100 DEGREES.
AFTERWARDS, THE UPPER LEVEL TROUGH RESPONSIBLE FOR RECENT RAINFALL
WILL MOVE E WITH AN UPPER RIDGE BUILDING INTO THE SRN ROCKIES. FLOW
BETWEEN FEATURES WILL BRIEFLY BECOME NWRLY THURSDAY EVENING AND
THURSDAY NIGHT. HEADING INTO FRIDAY, INCLUDING THE WEEKEND, THE
RIDGE WILL SHIFT EWRD BECOMING CENTERED OVER TOP THE REGION.
ON MONDAY THE UPPER RIDGE WILL SLIDE EWRD OVER THE TN/OH VALLEYS
WITH SW FLOW BRINGING LOW END POPS TO THE REGION AROUND THE
PERIPHERY OF HIGH PRESSURE THROUGH TUESDAY. CONVECTION IS EXPECTED
TO BE LIMITED TO THE AFTERNOON HOURS MAINLY DRIVEN BY DIURNAL
HEATING. THEREAFTER, THE UPPER RIDGE WILL RETROGRADE BACK INTO THE
REGION REDUCING AFTERNOON RAIN CHANCES.
THE MAIN STORY DURING THE PERIOD WILL BE AN INCREASE IN HEAT AND
HUMIDITY WHICH COULD RESULT IN HEAT RELATED ILLNESSES. AFTERNOON
HIGH TEMPERATURES ARE EXPECTED TO BE WELL INTO THE 90S WITH THE
HIGHEST READINGS OVER THE WEEKEND. OVERNIGHT LOWS ARE NOT EXPECTED
TO PROVIDE MUCH RELIEF WITH READINGS ONLY FALLING INTO THE LOWER

POINTS, HEAT INDEX VALUES ARE EXPECTED TO RANGE FROM 100 TO 105
DEGREES ON FRIDAY. HEAT INDEX VALUES SHOULD CREEP UPWARDS OVER THE
WEEKEND INTO EARLY NEXT WEEK WITH APPARENT T'S BETWEEN 105 TO 110
