.SHORT TERM...(MONDAY THROUGH TUESDAY NIGHT)
ISSUED AT 252 AM EDT SUN JUL 26 2015

(7/27)MONDAY...THE GFS CONTINUES TO BE THE ODD MODEL OUT WITH
PRINTING OUT PRECIPITATION WHILE THE ECMWF AND NAM INSIST ON IT
BEING DRY. CONSIDERING THE MOISTURE PROFILE FROM THE GFS SOUNDINGS,
IT`S LOOKING LIKE THERE IS SOME INSTABILITY AND THE MODEL IS
PRODUCING PRECIPITATION OUT OF THAT. HOWEVER, IT LOOKS LIKE THERE IS
ENOUGH CAPPING AND WITH NO FORCING THINK THAT THE DRY FORECAST IS
THE WAY TO GO. OVERNIGHT LOOKS TO REMAIN DRY ON ALL THE MODELS AS
THE 500 MB RIDGING LOOKS TO KEEP THE RAIN AT BAY WEST OF THE STATE.

THE DRYNESS SHOULD ALLOW FOR A SUNNY TO PARTLY CLOUDY SKY AND WARM
TEMPERATURES AS THE 850 MB TEMPERATURES RISE TO AROUND 20C WHICH
WOULD MIX OUT TO THE MID 80S TO LOWER 90S. WE HAVE 90 IN THE FORECAST
FOR AREAS ALONG AND SOUTH OF M-72. LOOKING AT THE ANALOGS, IT LOOKS
LIKE THERE THAT THE UPPER 80S IS GOOD.

(7/28)TUESDAY...IT LOOKS DRY DURING THE DAY TIME, BUT THERE IS A LOW
CHANCE THE MOISTURE INCREASE FROM THE RETURN FLOW THAT SOMETHING MAY
HAPPEN, BUT THE MAIN ACTION STILL LOOKS LIKE AT NIGHT WITH THE ONSET
OF THE COLD FRONT PUSHING INTO THE UPPER GREAT LAKES. BOTH THE GFS
AND THE ECMWF BIFURCATE THE BEST PRECIPITATION, SENDING IT NORTH AND
SOUTH OF THE FORECAST AREA. SO WILL SEE HOW THIS REACTS.

AGAIN THE TEMPERATURES FOR THE DAY LOOK WARM WITH TEMPERATURES
EXPECTED TO RUN BETWEEN THE MID 80S AND THE LOWER 90S. DEPENDING ON
THE CLOUD COVER, IT MAY BE A TOUCH COOLER THAN MONDAY. ALTHOUGH THE
850 MB TEMPERATURES ARE ABOUT THE SAME. THE ANALOGS HAVE THE BEST
CHANCE NEAR M-55 AND SOUTH FOR BETTER THAN 85 DEGREES. THE NUMBERS
NOW PEG MONDAY AS THE WARMEST OF THE NEXT 3 DAYS.

.LONG TERM...(WEDNESDAY THROUGH SATURDAY)
ISSUED AT 252 AM EDT SUN JUL 26 2015

EXTENDED (WEDNESDAY THROUGH SATURDAY)...WE LOOK TO BE GOING INTO A
COOLER PERIOD WITH THE ANALOGS STARTING ON WEDNESDAY POINTING TO A
SLOW DECENT INTO BELOW NORMAL TEMPERATURES AND AROUND NORMAL
PRECIPITATION INTO AND THROUGH THE NEXT WEEKEND. HERE ARE THE
DETAILS OF THE FORECAST...A PRETTY DECENT COLD FRONT PUSHES THROUGH
THE FORECAST AREA, AND COOLS THINGS DOWN AS THE 12Z 850 MB
TEMPERATURES FALL FROM 20C TO 00Z TO AROUND 15C. BY 12Z THURSDAY,
THE 850 MB TEMPERATURES WILL BE AROUND 9C. FRIDAY, A WEAK WARM FRONT
AND 500 MB SHORTWAVE TROUGH WILL MOVE THROUGH THE FORECAST AREA, AND
BRING MAINLY SHOWERS, BUT THUNDER CAN`T BE RULED OUT. TEMPERATURES
WILL BE UP A BIT, AT LEAST CLOSER TO NORMAL. SATURDAY, THE LOOKS
LIKE INITIALLY WILL CONTINUE DRY WITH THE THREAT FOR SOMETHING LATE
AT NIGHT.
