DISCUSSION
ISSUED AT 325 AM EDT TUE MAY 26 2026
AT THIS TIME, STILL WATCHING OUR EASTERN THIRD OF THE CWA FOR
ANY DEVELOPMENT OF MIST/FOG. WINDS HAVE BEEN CALM WHICH IS
LIKELY MITIGATING THE NEEDED MIXING TO HAVE ANY NOTABLE MIST/FOG
DEVELOPMENT. THIS ALSO SHOULD KEEP CONDENSATION NEAR SURFACE
LEADING TO PATCHES OF GROUND FOG AND DIRECT DEW DEPOSITION
INSTEAD. ALSO, HIGH CLOUDS ARE STREAMING NORTHWARD FROM A
SHORTWAVE CURRENTLY CENTERED OVER SOUTHERN ILLINOIS WHICH COULD
HELP REDUCE THE AMOUNT OF RADIATIONAL COOLING.
OTHERWISE, SHAPING UP TO BE A FAIRLY QUIET STRETCH WEATHER-WISE
OVER THE NEXT SEVERAL DAYS. AT THIS TIME THE ONLY POTENTIAL FOR
PRECIPITATION WILL BE LATE TONIGHT THROUGH WEDNESDAY AFTERNOON
WITH THE AFOREMENTIONED SHORTWAVE OVER SOUTHERN IL THAT WILL
MOVE EASTWARD AND JUST BRUSH THE SOUTHERN PORTION OF OUR AREA
WITH A FEW RAIN SHOWERS AND EVEN A FEW RUMBLES OF THUNDER
ESPECIALLY IN THE AFTERNOON. THIS THREAT OF PRECIPITATION SHOULD
STAY SOUTH OF US-30 AND THE BETTER CHANCES WILL BE SOUTH OF
US-24. NOW AT THE SAME TIME A TROUGH SWINGING SOUTHEAST OVER
EASTERN ONTARIO CANADA AND THE EASTERN GREAT LAKES WILL BRING
FAIRLY LOW CHANCES OF A SHOWER/THUNDERSTORM OVER OUR FAR
NORTHEASTERN MICHIGAN AND OHIO COUNTIES LATE WEDNESDAY.
FROM THURSDAY ONWARD, DRY CONDITIONS AND NEAR TO SLIGHTLY ABOVE
NORMAL TEMPERATURES (HIGHS IN THE 70S) WILL BE IN STORE ACROSS
THE REGION AS A BLOCKY OMEGA PATTERN DEVELOPS OVER CENTRAL NORTH
AMERICA. THE NEXT QUESTION WILL BE WHEN DOES THIS BLOCK START TO
BREAK DOWN AND GUIDANCE IS LIKELY TO PUSH FOR A MORE
PROGRESSIVE OUTCOME EVEN THOUGH BLOCKS CAN SET UP LONGER THAN
THE MODELS EXPECT IT TO. FOR NOW IN THE LONGER TERM DRY WEATHER
IS A LIKELY BET.
