Great summer weather to round out July
High pressure is slowly drifting into the Upper Mississippi Valley from Canada, bringing bright, mild weather for the last couple of days of the workweek. We'll enjoy abundant sunshine today with just a few fair-weather cumulus clouds and a slight northeast breeze that will draw in crisp, dry air, so humidity levels look to remain on the lower end of the summer scale. High temperatures will be in the lower 80s which is typical for this time of the year.
Weekend showers possible
A storm system will drag a cold front into the region for the weekend, bringing what may be the only rain chance for the next several days. Ahead of the front, slightly warmer, more humid air will spill into the area with high temperatures expected to reach the lower 80s Saturday afternoon. A few scattered showers and thunderstorms will develop later in the afternoon and especially later Saturday night as that cold front moves into the area. A few storms will then drift in behind the front for Sunday and rain chances will taper off by the midday hours. Rainfall totals will be fairly low, just enough to make a slight dent in our growing deficit over the past few weeks, but at least severe weather doesn't appear likely.
Thin clouds will slowly clear during the day Sunday with a cool northwest breeze ushering in Canadian air that will keep high temperatures several degrees below the seasonal average. Look for mid-70s Sunday afternoon and it looks like that type of temperature scheme may hang around into the upcoming workweek.
A taste of September next week
Strong high pressure from Canada will drift in and then plant itself in our region for the first half of next week, bringing sunny, mild weather to the area. High temperatures are expected to be in the mid and upper 70s and lows will be in the low to mid-50s, meaning we'll enjoy a healthy dose of natural air conditioning and we may be able to keep the windows open at night. A few isolated thunderstorms will be possible late next Thursday with a better chance of scattered storms will be possible Friday when warmer, more typical early August temperatures will return to the area.
