Sultry Period from This PM into Friday Night

Everything Growing....Including Pollen

Among all of the weather Minnesota has dealt with so far this summer (occasional oppressive heat, persistent humidity, frequent storms, occasional smoke), I haven't talked that much about growing. The details from the last US weekly crop bulletin (note that the Minnesota report was discontinued at the end of May) shows corn doing well and soybeans near average. Certainly, I noticed the corn tasseling in the St. Cloud area this week. And, everything that isn't flooded and blown down is a lush green. The only sobering note I've seen this week was a notice that Target was having large demand for allergy relief produced and had a per person limit. That I've noticed! And, we are merely approaching the ragweed season, the worst season of the year for many.

My allergies and current cold mean I will be relatively brief today.

Once again, my favored scenario from today through the weekend is:

1. Oppressive humidity and heat arriving today and continuing into late Friday night (heat advisory or warning likely tomorrow; a heat watch is already in effect and more area could be added)
2. Outbreak of severe storms possible from North Dakota into northern Minnesota tonight into tomorrow morning (1 in 5 chance of shower in central Minnesota tomorrow AM)
3. Better central Minnesota chance for showers and thunderstorms with possible heavy rainfall and severe weather Friday night into Saturday morning
4. Less humid, but still warm Saturday afternoon (slight chance for a shower)
5. Seasonably warm with noticeably to uncomfortable humidity Sunday
   1. Perhaps Canadian wildfire smoke from southern Alberta, but conditions right now aren't that bad (see EPA fire and smoke map)
6. Really uncertain early next week (remain near the storm track, so uncertain but frequent rain chances continue
