Indiana Weather Update 6-23-17

Rain and thunderstorm action moves through the state today. WE have a cold front pushing in from the north and west, and the remains of Tropical storm Cindy coming up from the south. Combined this will trigger rains of .5”-2” over the entire state today (rain totals go back to the start of the event last night, in some parts of the state). The good news is that this moisture moves out fairly quickly, giving a drier evening and a chance at a nice finish to the day.

Cooler air is in tomorrow and stays through the weekend. We should see good sunshine through the weekend, and only have a small concern about a few scattered to isolated showers tomorrow afternoon. The moisture that triggers those has a better likelihood of just producing clouds at this time. Temps will be below normal statewide tomorrow and Sunday, with better sky conditions Sunday.

Dry weather continues for the start of next week. In general, we have completely dry weather Monday through Wednesday over the northern half of the state. Monday and Wednesday will be dry in the south, but we have a few scattered showers moving in to southern Indiana on Tuesday. These showers will produce a few hundredths to .3” of rain with 50% coverage of areas from I-70 southward. Temps will be warming through the first half of next week.

Rains and strong storms produce totals of .5”-2” with 90% coverage Thursday from I-70 northward, and up to half an inch south of I-70 with 505 coverage. Then we follow up with another batch of showers and thunderstorms for Friday, that produce .5”-1.5” rain totals and 60% coverage. The least coverage for next Friday may end up being over the northeast quadrant of the state. Rain and thunderstorm action redevelops then for later Saturday afternoon and continues through Sunday bringing another .5”-1.5” of rain and 75% coverage. The moisture is rather impressive and the map above shows totals for next week from Tuesday morning through the weekend.

The extended period has lingering showers into next Monday (3rd) but a dry July 4th holiday. In fact, we should be dry for the 4th through the 6th statewide, with temps above normal. Then the remainder of the extended window gets more active again, with scattered showers and heat based thunderstorms developing for the 7th and 8th. However, there is not a good, well defined front arriving in there…and those will be interesting to watch for further development or degradation.
