A DYNAMIC LOW PRESSURE SYSTEM EXITING THE REGION IS RESULTING IN
IMPROVING CONDITIONS ACROSS THE AREA. NORTHERLY WINDS WRAPPING
AROUND THE BACKSIDE OF THE DEPARTING LOW WILL ALLOW COOLER,
DRIER AIR TO FILTER INTO THE REGION, KEEPING TEMPERATURES BELOW
NORMAL FOR THE NEXT FEW DAYS. SKIES WILL CLEAR FROM WEST TO EAST
THIS EVENING, AND GOOD RADIATIONAL COOLING WILL BRING OVERNIGHT
LOWS IN THE LOW TO MID 50S. TUESDAY WILL BE MILD WITH HIGHS IN
THE MID 70S.
THE LOW-LEVEL FLOW SHIFTS TO THE SOUTHWEST AGAIN ON WEDNESDAY,
AND WARM AIR ADVECTION AHEAD OF THE NEXT WEATHER SYSTEM WILL
FACILITATE HIGHS IN THE UPPER 70S. SHOWERS AND STORMS RETURN
WEDNESDAY EVENING, BUT WITH ONLY MARGINAL SHEAR AND INSTABILITY,
SEVERE WEATHER IS NOT EXPECTED, ALTHOUGH BRIEF HEAVY DOWNPOURS
ARE POSSIBLE. SCATTERED SHOWERS WILL REMAIN POSSIBLE THURSDAY

REGION. HIGH PRESSURE BUILDS BACK INTO THE MIDWEST ON SUNDAY AND
