DISCUSSION
ISSUED AT 158 PM EDT WED APR 29 2026
A GENERAL WEST TO NORTHWEST FLOW ALOFT WILL KEEP THE REGION IN A
COOLER AND MUCH LESS ACTIVE PATTERN FOR THE NEXT 7 DAYS OR MORE.
THAT'S NOT TO SAY THERE ISN'T A FEW ITEMS TO LOOK AT, BUT IN
COMPARISON TO THE PAST SEVERAL WEEKS IT IS A WELCOME BREATHER.
A SERIES OF WEAK DISTURBANCES WILL HELP KEEP PERIODS OF CLOUDS AND
EVEN SOME LIGHTER SHOWERS AROUND THIS AFTERNOON/EVENING AS WELL AS
LATER THURSDAY AFTERNOON INTO THURSDAY NIGHT. QPF AMOUNTS WILL BE ON
THE LIGHT SIDE AND NOT CAUSE ANY CONCERNS WITH THE HYDRO ISSUES
STILL IN PLAY FOR SOME AREAS. TEMPERATURES WILL BE CHILLY (AND
GENERALLY BELOW NORMAL) FOR LATE APRIL AND IN COMPARISON TO RECENT
TIMES. ALTHOUGH LOWS BOTH TONIGHT AND THURSDAY NIGHT WILL DIP INTO
THE 30S, CLOUD COVER, LIGHT PRECIP AND A MODEST BREEZE SHOULD LIMIT
ANY FROST POTENTIAL.
A SOMEWHAT MORE PRONOUNCED TROUGH PUSHES THROUGH FRIDAY, BRINGING
WITH IT ADDITIONAL CAA AND MORE IMPORTANTLY CLEARING SKIES AS WELL
AS DIMINISHING WINDS. THIS WILL SET THE STAGE FOR WIDESPREAD FROST
DEVELOPMENT WITH SOME AREAS IN THE NE POSSIBLY GOING BELOW FREEZING
FOR A LIGHT FREEZE. TOO EARLY FOR ANY HEADLINES, BUT SUSPECT AT
LEAST A FROST ADVISORY WILL BE HOISTED AT SOME POINT WITH MAYBE A
NEED FOR A FREEZE WATCH/WARNING. THE COOL CONDITIONS WILL PERSIST
INTO SATURDAY BEFORE THE DEEPER TROUGH BEGINS TO PUSH NORTH AND SOME
MODERATION BACK TO MORE NORMAL TEMPERATURES (60S) ARRIVE.
DISTURBANCES WILL STILL MOVE THROUGH THE FLOW AND BRING SOME CHANCES
FOR SHOWERS NEXT WEEK.
AVIATION /18Z TAFS THROUGH 18Z THURSDAY/
ISSUED AT 140 PM EDT WED APR 29 2026
MVFR/VFR CIGS CONTINUE THROUGH 12Z THU FOR KSBN AND 16Z THU FOR
KFWA WITH PERIODS OF LIGHT SHOWERS AS A DISTURBANCE MOVES
EASTWARD THROUGH THE AREA. SOME SLIGHT REDUCTIONS IN VSBYS WITH
THE HEAVIER SHOWERS. THERE IS LOW CHANCES OF AN EMBEDDED
THUNDERSTORM MAINLY FOR KFWA LATER THIS AFTERNOON AND EVENING
HOWEVER, VERY LOW CONFIDENCE WITH THIS OUTCOME SO DID OPT TO
KEEP MENTION OUT OF THE FORECAST AT THIS TIME. NORTHWESTERLY
WINDS CONTINUE AROUND 10 KTS, HOWEVER FOR KFWA AFTER 16Z THU
LOOK TO SEE AN UPTICK IN DIURNALLY DRIVEN GUSTS TO AROUND 20
KTS.
