DISCUSSION
ISSUED AT 230 PM EDT WED APR 1 2026
ISOLATED TO SCATTERED SHOWERS AND STORMS ARE ONGOING ACROSS THE
AREA. THIS ACTIVITY WILL CONTINUE THROUGH THIS EVENING. THE GREATEST
THREAT FOR AN ISOLATED STRONG STORM WILL BE ALONG THE TN/KY STATE
LINE AND INTO SOUTHWEST VA. THESE AREAS ARE WHERE WEAK,
EFFECTIVE, 0-6KM SHEAR OF AROUND 15KTS OVERLAPS WITH MODERATE
INSTABILITY. THERE IS A LOW PROBABILITY OF AN ISOLATED DAMAGING
WIND GUST ACROSS THESE AREA ALONG WITH SMALL HAIL. THE HIGHER
SHEAR VALUES WILL REMAIN FURTHER NORTH INTO KY THROUGH THE REST OF
TODAY. A FEW STRONG STORMS WILL ALSO BE POSSIBLE ELSEWHERE DUE TO
THE MODERATE INSTABILITY, BUT AGAIN LOW PROBABILITY OF ANY SEVERE
WEATHER.
WITH THE STRONG RIDGE OF HIGH PRESSURE IN PLACE TO OUR EAST, THE
ABOVE NORMAL WARMTH CONTINUES TOMORROW THROUGH SATURDAY.
ADDITIONAL CHANCES FOR ISOLATED TO SCATTERED SHOWERS AND STORMS
WILL BE IN PLACE EACH DAY. NO SEVERE WEATHER IS EXPECTED DUE TO
THE ABSENCE OF SHEAR.
A COLD FRONT WILL REACH THE FORECAST AREA SOMETIME LATE SATURDAY
INTO EARLY SUNDAY. THE OVERALL SEVERE THREAT CONTINUES TO REMAIN
LOW DUE TO THE EXPECTED TIMING (OVERNIGHT ARRIVAL) OF THE SHOWERS
AND STORMS AND THUS LIMITED INSTABILITY. THOUGH NO SPC OUTLOOKS
ARE IN PLACE AT THE MOMENT, WPC CONTINUES TO HIGHLIGHT A MRGL
RISK (5% PROBABILITY) FOR FLASH FLOODING FOR THE NOW DAY 4 PERIOD.
CURRENT NBM PROBS FOR AT LEAST 1 INCH OF RAIN WITH THE FRONTAL
PASSAGE RANGE FROM 35 TO 55% FOR MOST AREAS. LOWER PROBS OF 15 TO
25% ARE IN PLACE ACROSS NORTHEAST TN AND PORTIONS OF SOUTHWEST
VA.
FOLLOWING THE FRONT, COOLER MORE SEASONABLE TEMPERATURES BEGINNING
EASTER SUNDAY TO KICK START THE FIRST FULL WEEK OF APRIL. A DRY FEW
DAYS MAY SET IN WITH LOW AFTERNOON RHS, SO A POSSIBLE RETURN OF
ENHANCED FIRE DANGER. FROST DEVELOPMENT MAY EVEN BE POSSIBLE SOME
MORNINGS EARLY NEXT WEEK.
