DISCUSSION
ISSUED AT 233 AM EDT THU APR 2 2026
TODAY WILL BE MUCH LIKE YESTERDAY, EXCEPT MAYBE LESSER COVERAGE IN
HIGHER TERRAIN STORMS. ACCORDING TO THE 00Z HRRR, INSTABILITY WILL
BE WEAKER. ANY STORM THAT DOES FORM THOUGH DOES HAVE THE CHANCE OF
BECOMING STRONG WITH PRIMARY HAZARDS BEING GUSTY WINDS, SMALL HAIL,
DOWNPOURS, AND LIGHTNING. BASICALLY THE SAME CAN BE SAID FOR FRIDAY
WITH A DIURNAL INCREASE IN ISOLATED TO SCATTERED SHOWERS AND STORMS.
SOUTHERLY TO SOUTHWESTERLY WINDS AND GUSTS COULD BE HIGHER TODAY DUE
TO A LOW PRESSURE CENTER MOVING TOWARDS LAKE MICHIGAN AND THE
SURFACE HIGH REMAINING ANCHORED OVER THE WESTERN ATLANTIC.
EVEN WITH A SHORTWAVE TROUGH MOVING TOWARDS THE WESTERN GREAT LAKES
LATER TODAY, WE WILL REMAIN MOSTLY UNDER THE INFLUENCE OF THE UPPER
RIDGE WITH VERY WARM TEMPERATURES CONTINUING. LOW TO MID 80S FOR
MOST, EXPECTED EACH DAY THROUGH SATURDAY. THESE VALUES RUN 15 TO 20
DEGREES ABOVE NORMAL FOR EARLY APRIL.
A PATTERN CHANGE ARRIVES THIS WEEKEND WHEN A DEEPER TROUGH IS
FORECAST TO TAKE A NORTHERN PLAINS TO WESTERN GREAT LAKES TRACK. A
DEEPENING LOW PRESSURE CENTER NEAR THE CENTRAL US WILL ALSO TRACK
TOWARDS THE GREAT LAKES. A TRAILING COLD FRONT WILL REACH THE
FORECAST AREA SOMETIME LATE SATURDAY INTO EARLY SUNDAY. THE
POTENTIALLY STRONG FRONTAL SYSTEM WILL HOPEFULLY BRING MUCH NEEDED
PRECIPITATION AREA-WIDE. SOME LOCATIONS COULD SEE UP TO OR JUST OVER
ONE INCH OF RAINFALL. ALTHOUGH IT IS STILL TOO EARLY TO KNOW IF
STRONG TO SEVERE STORMS WILL ACCOMPANY THIS SYSTEM, WPC HIGHLIGHTS A
MRGL RISK FOR FLASH FLOODING FOR THE DAY 4 PERIOD.
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. A SECONDARY COLD FRONT AROUND TUES/WED MAY
BRING EVEN COLDER TEMPERATURES TO THE AREA WEDNESDAY MORNING. FOR
EXAMPLE, TRI-CITIES AVERAGES A LOW OF 41 DEGREES APRIL 8TH, BUT THE
CURRENT FORECAST IS CALLING FOR LOW 30S.

(12Z TAFS)
ISSUED AT 706 AM EDT THU APR 2 2026
MVFR FOG HAS DEVELOPED AT TRI BUT IS EXPECTED TO DIMINISH IN THE
NEXT HOUR OR TWO. OTHERWISE, SOUTHERLY TO SOUTHWESTERLY WINDS WILL
INCREASE THROUGH THE DAY WITH MID LEVEL CLOUDS. LOW-END RAIN
CHANCES WILL ALSO RETURN BUT STILL LEFT OUT OF THE TAFS. TRI HAS
THE GREATEST CHANCE FOR ANY IMPACT. LIGHTER WINDS AND SIMILAR
CONDITIONS ARE EXPECTED AGAIN TONIGHT.
