DISCUSSION
SUBSIDENCE AND HEIGHT RISES TODAY START A FEW DAY WARMING TREND
WHERE TEMPERATURE REACHES SEASONAL AVERAGE READINGS BY MONDAY.
DIURNAL MIXING MAY FOSTER 15 TO 20 MPH AFTERNOON WINDS WHILE
LOWERING HUMIDITY VALUES TO NEAR 30 PERCENT, BUT RESIDUAL GROUND
SATURATION PRECLUDES ANY FIRE WEATHER CONCERNS.
WEAK SHORTWAVE MOVEMENT AND A POTENTIAL LIFTING WARM FRONT MAY
RESULT IN SCATTERED CONVECTION MONDAY AFTERNOON AND EVENING THAT
FAVORS EASTERN OHIO. MORE WIDESPREAD RAIN AND FALLING TEMPERATURE
IS EXPECTED LATE TUESDAY INTO THE LATER HALF OF THE WEEK AS GREAT
LAKE TROUGHING RETURNS.
