Rain arrives today and will change our weather pattern just a bit. A strong cold front is working across the corn belt from northwest to southeast and has some significantly cooler air with it. We are going to leave rain totals alone this morning for the coming 18 hours or so. We see rains of .25”-1” with coverage at 80%. We are not quite as concerned about thunderstorms but will grant you that we can’t rule them out. The map above shows rain totals through midnight tonight.
We are going drier tomorrow, as the airmass change coming behind this front looks to be more substantial. We think we see mixed clouds and sun for both tomorrow and Friday, but no significant precipitation threat. Temps will actually be below normal for these days, quite the contract from earlier in the week. This cold front just has not seen its edge erode away, and the airmass has not modified as it has trekked across the corn belt so far…so we are making this tweak.
Warm and humid weather returns over the weekend as south flow works back into the area. We also see scattered showers and thunderstorms moving through, favoring the northern half of the state. Precipitation potential has a wide range at this point, anywhere from a tenth to 1 inch combined for the 2 day period. However, coverage is only 60%, and that again is skewed north. Southern Indiana likely escapes with nothing. Temperatures will return to above normal levels this weekend.
Monday should be dry. However, we see that general unsettled weather pattern we have mentioned before (pretty much every day this week) back over the area for the rest of the week. This yields scattered showers for Tuesday and Wednesday at least, producing .25”-.5” rain totals each day, and nearly 70% coverage each day too. This set up does not bring rain all day, but chances are there through each day, Tuesday and Wednesday. We should be mostly dry Thursday, but then a minor front is back, threatening for Friday. The moisture with the Friday front is not impressive yet, but we think it may be able to build as we get closer to the end of next week. We have no reason to deviate from our thoughts on an active extended period too, keeping scattered showers as at least a possibility at least 4 days of that 11-16 day period.
Temps will mostly be above normal for the next 10 days to 2 weeks. We are cooler today than previous days and will be below normal tomorrow and Friday, but then we spend the rest of the forecast period anywhere from 2-8 degrees above normal.
