THE SCHOOL WILL ALSO OFFER A LIVE STREAM OF THE EVENT. <NOW NBC5 FIRST WARNING WEATHER WITH CHIEF METEOROLOGIST TOM MESSNER> TOM IS IN THE PLATTSBURGH STUDIO TONIGHT. TOM… (áááWALLááá) ———————- SHOWERS WILL QUICKLY WANE AFTER DARK WITH DEPARTURE OF A PIECE OF UPPER-LEVEL ENERGY AN LOSS OF DAYTIME HEATING. SURFACE HIGH PRESSURE OVER THE MIDWEST WILL NOSE EASTWARD TONIGHT. WITH NO ADDITIONAL ORGANIZED UPPER-LEVEL SYSTEMS MOVING THROUGH THE REGION IN LIGHT NORTHWES FLOW, WE SHOULD SEE MAINLY CLEAR SKIES SUPPORTING COLD AND CALM CONDITIONS SUFFICIENT FOR FROST WITH LOW TEMPERATURES BETWEEN 32 AND 36 IN MANY AREAS. THEREFORE, THE FROST ADVISORY REMAINS IN EFFECT FOR THE EARLY MORNING HOURS ACROSS THE SAINT LAWRENCE VALLEY AND PORTIONS OF CENTRAL, NORTHWEST, AND SOUTHERN VERMONT WHERE THE GROWING SEASON HAS BEGUN. WET SURFACE CONDITIONS WHERE SHOWERS WERE MOST PROLIFIC TODAY COULD SUPPORT FOG GIVEN THE EXPECTED RADIATIONAL COOLING, BUT THE POSSIBILITY IS LOW ENOUGH TO EXCLUDE FROM THE FORECAST AT THIS TIME. FOR TOMORROW, THE DAYTIME SHOULD BE QUITE PLEASANT WITH ANOTHER DAY OF MODEST BREEZES BUT WITH MORE SUNSHINE AND HIGHER TEMPERATURES. HIGHS WILL BE WELL INTO THE 60S IN MOST POPULATED LOCATIONS AND AGAIN RELATIVELY CHILLY AT ELEVATION DUE TO DEEPLY MIXED AIR. FOR AREAS NEAR THE INTERNATIONAL BORDER, SOME INTERESTING WEATHER WILL ARRIVE TOWARDS EVENING, AS A WIDE ARRAY OF MODEL GUIDANCE DEPICTS AN ORGANIZED CLUSTER OF SHOWERS WITH EMBEDDED THUNDER DROPPING SOUTHWARD. HAVE GONE WITH GUSTY SHOWERS WITH A SLIGHT CHANCE OF THUNDER AS CONVECTIVE POTENTIAL IS MARGINAL FOR THUNDERSTORMS, BUT THERE APPEARS TO BE SUFFICIENT WIND SHEAR TO SUPPORT STRONG (UP TO 35-40 MPH) WINDS, ESPECIALLY WITH RELATIVELY DRY LOW LEVEL AIR IN PLACE. AS THE SHOWERS CONTINUE SOUTHWARD AFTER DARK, THEY SHOULD WEAKEN NEAR OR SOUTH OF THE CHAMPLAIN VALLEY. OTHERWISE, THURSDAY NIGHT SHOULD BE QUIET WITH ENOUGH WIND AND CLOUD COVER TO PREVENT TEMPERATURES FROM GETTING BELOW THE 35 TO 45 RANGE. && .SHORT TERM /FRIDAY THROUGH SUNDAY/… AS OF 324 PM EDT WEDNESDAY… MAIN STORY FOR THE END OF THE WORK WEEK INTO THE WEEKEND WILL CONTINUE TO BE THE TREND OF TEMPS WARMING BACK TO NORMAL OR SLIGHTLY ABOVE, ALONG WITH CHANCES FOR AFTERNOON CONVECTION EACH DAY. LATEST MODEL TRENDS SHOW EVER SO SLIGHTLY RISING MID/UPPER LEVEL HEIGHTS FRIDAY WITH VERY WEAK FLOW BELOW 700MB. THIS WOULD TEND TO LEAN TOWARDS LESSER CHANCES FOR PRECIPITATION, BUT SOUNDINGS CONTINUE TO SUPPORT THE IDEA OF ISOLATED TO SCATTERED TERRAIN DRIVEN SHOWERS DEVELOPING IN THE AFTERNOON AS SOME WEAK ELEVATED INSTABILITY DEVELOPS. ANYTHING THAT DOES FORM WILL DISSIPATE RAPIDLY IN THE EVENING THOUGH FOR A QUIET OVERNIGHT. FOR THE WEEKEND, IT’S BASICA
