Indiana Weather Outlook 4-20-17


gfs_pr6_slp_t850_indy_6A cold front works its way through the state from NW to SE today, and will be responsible for the development of scattered showers. Rain totals are likely in the .1”-.5” range with coverage at 75% of the state. We have to keep an eye out for a few thunderstorms this morning in NE Indiana, but in general, this frontal passage will be storm free. The map above shows a snapshot of potential frontal positioning and rains as of early this evening.

Dry over a good chunk of the state for Friday, although action does start to build back in over southern Indiana later tomorrow afternoon. Rains coming with a large system out of the central plains will be in for late Friday through the weekend. These rains look most impressive from I-70 southward where we can see easily .5”-1.5” and some thunderstorm development from Friday night through Sunday midday. North of I-70 chances are significantly lower. WE might see some lighter rains up to US 24, but they will be under a quarter of an inch for the most part. North of US 24, there will not be too much precipitation this weekend, at least the way the system is tracking right.

Dry weather remains on track to be in for Monday through Thursday of next week. Some models are trying to increase cloud cover or Tuesday afternoon and Tuesday night, triggering a few scattered showers, but we think that is likely overdone. WE like the dry period through the first 4 days of the week. That changes later for Friday, though, as a strong front is on the way in again. This front brings rains for late the 28th through the 30th and we still think it has the potential for .25”-1” rain totals and 80% coverage.

In the extended period, we like a minor front for the 3rd-4th of May, but in general, a less active period that should allow for better field work potential.
