DISCUSSION
ISSUED AT 149 PM EDT TUE APR 28 2026
A SERIES OF MID & UPPER-LEVEL DISTURBANCES WILL BRING ONE MORE
CHANCE FOR SCATTERED SHOWERS AND A FEW THUNDERSTORMS TO THE REGION
FROM LATE TONIGHT THROUGH WEDNESDAY. MODELS ARE IN GOOD AGREEMENT
WITH MOST AREAS SEEING AT LEAST MEASURABLE PRECIPITATION, ALTHOUGH
THE BEST CHANCE (>50%) OF AT LEAST 0.25 INCH APPEARS TO BE FOCUSED
MAINLY ALONG/SOUTH OF US-24 PER THE LATEST HREF SUITE. NOT EXPECTING
THIS ADDITIONAL RAINFALL TO RESULT IN ANY INCREASE TO ONGOING HYDRO
CONCERNS. OTHERWISE, PRECIPITATION CHANCES APPEAR TO BE FAIRLY LOW
THROUGH THE REMAINDER OF THE WEEK, THOUGH A LIGHT SHOWER OR TWO MAY
BE POSSIBLE AT TIMES WITH A FEW PASSING WAVES IF SUFFICIENT MOISTURE
IS PRESENT. GENERAL TROUGHINESS ALOFT WILL KEEP TEMPERATURES ON THE
COOLER SIDE FOR SOME TIME, WITH A THREAT FOR FROST OVER THE NEXT FEW
DAYS STARTING WEDNESDAY NIGHT. THE BEST CHANCE FOR A POSSIBLE FREEZE
CURRENTLY LOOKS TO BE FRIDAY NIGHT INTO SATURDAY MORNING, BUT
OVERALL CONFIDENCE IN A HARD FREEZE IS LOW AT THIS TIME.
