After a hot, humid and partially stormy weekend (Sunday was hottest day of the summer thus far at Cape Girardeau with an official high of 95°) another unusually nice pattern will be developing for the next several days...starting this morning.
The jet stream is once again (the pattern of 2014) developing into an unusually amplified (for summer, anyway) western ridge/eastern trough pattern. This will bring northwest flow to the mid-Mississippi Valley and the Heartland. Combined with a light northerly surface flow, this will bring lower dew points/humidity and cooler conditions to our region for much of the upcoming week.
In the short term, a few cumulus clouds will likely develop from late morning through evening today, but with a nice north breeze, lower dew points and afternoon highs in the U70s north to M80s south, an unusually pleasant late July day is in the works to start the workweek.
Tonight will be clear...and with light winds and low dewpoint temps, it will be unusually cool for mid-summer. Daybreak lows Tuesday morning will be in the 50s to L60s.
One potential issue with the forecast for the next week or so....the northwest flow pattern will gradually weaken into the weekend but will not completely disappear until early next week...according to latest model runs. If this holds, there will be little chance of significant rainfall for the foreseeable future....at least until we get back to warmer and more humid pattern next week..in early August. So areas that haven't had rain recently may have to go several more days with dry weather.
By next weekend (first weekend of August) we should be a bit warmer again...but the overall trend still looks relatively pleasant...with slightly below average temps and dew points for early August.
