WHAT HAS CHANGED
STILL TRACKING THE EVOLUTION OF THE CONVECTION ACROSS THE CWA THIS
EARLY PRE-DAWN MORNING.

ENHANCED SHOWERS TONIGHT.

OVER THE WEEKEND.
DISCUSSION
KEY MESSAGE 1...
WILL BE FOCUSING THIS PART OF THE FORECAST IN THE WAKE OF THE
ONGOING CONVECTIVE ACTIVITY IN THE GREAT LAKES. LOW PRESSURE TO
SHIFT TO THE EAST OF THE CWA TODAY WITH A COLD FRONT COMING THROUGH
ACROSS LAKE ERIE BY 18Z TODAY. EXPECT SOME ADDITIONAL CONVECTIVE
ACTIVITY ALONG THE COLD FRONT BUT THE POSSIBILITY FOR SEVERE AT THIS
POINT SHOULD BE GREATLY DIMINISHED. STORMS THAT FORM WILL BE
FIGHTING DRY AIR ALOFT AND LIMITED INSTABILITY, BUT THUNDER SHOULD
STILL BE EXPECTED IN A SCATTERED NATURE AS THE COLD FRONT TRACKS
THROUGH. FROM THERE, THE WHOLE STACKED LOW PRESSURE SYSTEM TO THE
EAST WILL STRENGTHEN, AND CREATE A BRIEF PERIOD WHERE WEAK TROUGH
AXES ROTATING THROUGH IN THE CYCLONIC FLOW AND COOL AIR OVER THE
WARM LAKE WILL PRODUCE LAKE ENHANCED SHOWERS LATE THIS EVENING INTO
TONIGHT. EXPECTING A SMALL AMOUNT OF NEAR SURFACE BASED CAPE CAPPED
AT AROUND 800MB WITH AN INVERSION AT THAT LEVEL. HIGH PRESSURE
BUILDING FROM THE WEST WILL SHUT THIS POTENTIAL FOR SHOWERS DOWN
FAIRLY QUICKLY.
KEY MESSAGE 2...
HIGH PRESSURE AND DRY WEATHER WITH A COOLER AIRMASS SETTLES INTO
PLACE FOR THE END OF THE WEEK. CONDITIONS WILL BEGIN TO BECOME
UNSETTLED OVER THE WEEKEND WITH A 500MB TROUGH MOVING INTO THE GREAT
LAKES VIA THE UPPER MISSISSIPPI VALLEY ACCOMPANIED WITH AN INVERTED
SURFACE TROUGH FROM SURFACE LOW PRESSURE OVER THE LOWER MISSISSIPPI
VALLEY. WILL EXPECT CONVECTIVE CHANCES TO INCREASE WITH GRADUALLY
RISING DEWPOINTS ONCE AGAIN AND TEMPERATURES BACK INTO THE LOW TO
MID 80S.

EVENING INTO TONIGHT FOLLOWING THE PASSAGE OF A SECONDARY COLD
