PATTERN SYNOPSIS AND FORECAST:
UPPER LOW AND LONG WAVE TROUGH ACROSS CANADA WILL CONTINUE WITH
DEPRESSED HEIGHTS AND COOL AIR ALOFT OVER NORTHERN MI TODAY. THAT
BEING SAID, THIS FEATURE WILL SLOWLY RETREAT NORTHWARD WITH TIME,
BEING REPLACED WITH WARMER TEMPS ALOFT. THERE WILL STILL BE STEEP
ENOUGH LAPSE RATES FOR A FEW SHOWERS, AND THIS WILL BE ESPECIALLY
TRUE ACROSS EASTERN UPPER IN THEORY. HAVE POPS FROM BASICALLY NEAR
AND JUST NORTH OF M-32 TO THE E UP WITH PERIODIC SHOWER CHANCES. A
SMALL AND SUBTLE SHORT WAVE ON THE SOUTHERN MOST PERIPHERY OF THE
TROUGH MAY ACTUALLY BE THE CATALYST FOR A FEW SHOWERS THIS
AFTERNOON. DESPITE A SOMEWHAT SIMILAR THERMODYNAMIC ENVIRONMENT
COMPARED TO WEDNESDAY, TODAYS SHOWERS WILL NOT HAVE THE SAME SPATIAL
CONTINUITY NOR VIGOR OF YESTERDAYS CONVECTION. EXPECT LARGELY
ISOLATED SHOWERS/LOW TOPPED CONVECTION TODAY ACROSS THE
AFOREMENTIONED AREAS. ADDITIONALLY, RELATIVELY TIGHT PRESSURE
GRADIENT BETWEEN A SFC LOW PRESSURE SYSTEM IN CANADA (UPPER LOW) AND
BROAD SFC HIGH PRESSURE ACROSS THE PLAINS, RELATIVELY DEEP BOUNDARY
LAYER HEIGHTS, AND A RIBBON OF 20-30KT H850 WINDS WILL RESULT IN
BREEZY CONDITIONS THROUGH THE DAY TODAY.
A FEW SHOWERS MAY TRY TO CLIP THE E UP DURING THE FIRST HALF OF THE
OVERNIGHT, BUT ANY ACTIVITY DURING THE AFTERNOON AND EVENING HOURS
SHOULD WANE THROUGH THE NIGHT IN A GENERAL SENSE. COOL NIGHT
EXPECTED AS WELL WITH TEMPS IN THE 30S ACROSS THE INTERIOR.
TROUGH CONTINUES TO EVACUATE TO THE NORTHEAST ON FRIDAY, REPLACED BY
INCREASING HEIGHTS ALOFT. CONSEQUENTLY, EXPECT A FEW DEGREES OF
WARMING COMPARED TO THURSDAY, ALONG WITH DRY CONDITIONS. THIS WILL
BE THE START OF THE EXCELLENT WEEKEND FORTHCOMING. HEIGHTS CONTINUE
TO RISE THIS WEEKEND DUE IN PART TO DEEP TROUGHING DIVING OVER THE
PACNW. SFC REFLECTION WILL BE AN ELONGATED, BUT DOMINANT, LOW
PRESSURE SYSTEM THAT MEANDERS ACROSS THE PLAINS AND VICINITY.
MEANWHILE, HIGH PRESSURE SHIFTS TO THE EAST ACROSS THE NORTHEAST.
CONSEQUENTLY, SOUTHERLY WINDS ARE ANTICIPATED, BREEZY TO WINDY AT
TIMES AS LOW LEVEL WINDS SPREAD OVER N MI, WITH TEMPERATURES SOARING
INTO THE 70S BOTH WEEKEND DAYS. THE ONLY FEATURE THAT WILL NEED TO
BE WATCHED WILL BE THE REMNANTS OF A TROPICAL SYSTEM THAT WILL
IMPACT THE GULF, WHICH WILL MOVE NORTHEAST ACROSS THE OH VALLEY,
THEN EAST ACROSS THE MID-ATLANTIC. THIS LOW PRESSURE SYSTEM SHOULD
BE DISCONNECTED ENOUGH FROM TROUGHING TO THE NORTH ACROSS CANADA
THAT IT SHOVES OFF TO THE EAST AND DOES NOT IMPACT US THAT MUCH. ONE
LOCATION TO WATCH FOR A STRAY SHOWER WOULD BE SAGINAW BAY. THIS
WOULD BE ON SUNDAY.
HEADING INTO EARLY NEXT WEEK, RIDGING BUILDS ACROSS THE DEEP SOUTH,
AND MORE GENERALLY ACROSS PORTIONS OF THE NATIONS MID-SECTION. AT
THE SAME TIME, TROUGHING ACROSS ONTARIO SHIFTS SOUTHWARD, WITH
ASSOCIATED FRONTAL BOUNDARY AND PRECIPITATION CHANCES RETURNING TO
NORTHERN MI. CURRENT PROGGED PATTERN SUGGESTS THE BEST CHANCE FOR
RAIN WILL BE MONDAY AND MONDAY NIGHT, BUT THIS WILL BE FINE TUNED
GOING FORWARD. COLD ADVECTION BEHIND THIS SYSTEM AND FRONTAL
BOUNDARY WILL RETURN TEMPERATURES BACK TO SEASONAL NORMAL BY TUESDAY,
AND REALLY THROUGH THE MID WEEK TIME FRAME.
