An area of high pressure will build into the region today, but a small packet of atmospheric energy will also slide through.
There are some thin clouds moving into the area this morning as this energy approaches. It should remain dry through the early afternoon, however. This will allow time for the daytime heating to build to sufficient levels to pop a few showers and small thunderstorms by the mid-afternoon.
Many areas will not see rain today, and most of the showers should be light and short-lived. A few rumbles of thunder and briefly heavier rains will be possible. Severe weather is not expected. The southern half of the region seems to be slightly favored for the development of these showers.
Otherwise, expect a mix of sun and clouds. Temperatures will push into the low and mid 80s this afternoon.
Showers and clouds will quickly dissipate as the daytime heating is lost this evening. Mostly clear skies, with some areas of patchy fog, are expected through the overnight.
Temperatures should drop to the upper 50s and low 60s, as has been commonplace lately.
Winds both during the day and night will be light with speeds at or under 5 mph. Daytime winds will be from varying directions, while the nighttime wind will be southerly.
Sunshine and southwest winds on Wednesday will help push temperatures upward. A few urban areas may flirt with 90 degrees, while the rest of the region reaches the mid and upper 80s. Even higher elevations should reach 85 degrees.
Dewpoints will range from the mid 50s to the mid 60s, so it may feel a bit muggy at times, but not oppressively so. No rain is expected during the day on Wednesday.
A Couple Chances for Storms
Wednesday afternoon and evening, thunderstorms will develop over the Upper Great Lakes. What is left of these storms will move through sometime Wednesday night, most likely after midnight.
Widespread rain and thunder will be possible as this moves through, and some of the rain could linger into Thursday morning.
This sets up a highly uncertain Thursday. The interaction of these thunderstorm leftovers on the environment is highly complex and cannot be fully understood until the path and nature of these leftovers are realized. This is likely to remain a reduced confidence situation until it unfolds.
Additional showers and thunderstorms will be possible on Thursday. While the threat for severe weather is currently higher to our east, with strong winds aloft, the threat will need to be monitored.
However, it could very well end up being that morning clouds and showers torpedo the daytime heating necessary for robust afternoon storms. Stay tuned.
Due to this complex of thunderstorms and the potential for additional activity in the afternoon, the temperature forecast has come down significantly for Thursday. Highs are now expected to top out in the mid 80s.
Friday, instead, will be the hottest day of the week. Precipitation is not expected and there should be plenty of sunshine. Highs will be near or above 90 degrees for many areas.
Another stormy day will be possible on Saturday as a cold front moves through. The timing of the front will likely play a significant role in whether or not we see strong thunderstorms.
Cooler weather will build in behind the front with highs in the mid 70s Sunday and Monday. Both days look mostly dry.
Temperatures next week should stick close to average with low chances for rain.
