NATIONAL WEATHER SERVICE NORTHERN INDIANA
249 PM EDT SUN AUG 23 2015

.SYNOPSIS...
ISSUED AT 245 PM EDT SUN AUG 23 2015

A COLD FRONT WILL MOVE EAST OF THE AREA THIS EVENING BRINGING
SHOWERS AND THUNDERSTORMS TO AN END AND ALLOWING SKIES TO CLEAR
OVERNIGHT. AN UPPER LEVEL DISTURBANCE WILL MOVE ACROSS THE WESTERN GREAT

BE WITH INITIAL LINE MOVE THROUGH ERN PORTION OF CWA LATE THIS
AFTN. ALTHOUGH MODERATE INSTABILITY SHOULD BE AVAILABLE AS THE
CONVECTION MOVES THROUGH... 0-6KM SHEAR MARGINAL AT 25-30KT AND
WITH MID LEVEL LAPSE RATES UNDER 6C/KM... ONLY ISOLATED SVR STORMS
EXPECTED... WITH DAMAGING WINDS THE MAIN THREAT. SKIES SHOULD
CLEAR QUICKLY BEHIND THE FRONT THIS EVE WITH JUST PATCHY CU/STRATO
CU OVERNIGHT. STRONG CAA OVERNIGHT SHOULD ALLOW TEMPS TO FALL TO
THE L-M50S BY DAYBREAK MONDAY.

VORT LOBE ROTATING AROUND THE LAKE SUPERIOR UPR LOW ACROSS SRN MI
MONDAY AFTN ACCOMPANIED BY CYCLONIC WNW LOW LEVEL FLOW AND WK LAKE
INDUCED INSTABILITY MAY ALLOW WIDELY SCT SHOWERS ACROSS NRN ZONES IN

PLACE THE LOCAL AREA ON THE SW FRINGE OF DEEP/COLD CYCLONIC FLOW
WITH TEMPERATURES WELL BELOW NORMAL FOR LATE AUGUST STANDARDS. THIS
CYCLONIC FLOW AND SOME LAKE CONTRIBUTION (WNW FLOW AND LAKE-7H TEMP
DIFFERENTIALS PUSHING 20C) SHOULD ALLOW FOR A HEALTHY CU FIELD EACH
DAY...ESPECIALLY ACROSS FAR NORTHERN ZONES WHERE A FEW DIURNALLY/LE
DRIVEN SHOWERS NOT OUT OF THE QUESTION. THE SECOND HALF OF THE WEEK
WILL FEATURE A GRADUAL WARMING TREND AND MAINLY CLEAR SKIES AS THE
ABOVE MENTIONED STACKED LOW LIFTS OUT ALLOWING LOW LEVEL RIDGING TO
BECOME BETTER ESTABLISHED.
