Forecast by Blake Cotcamp (bcotcamp@purdue.edu)

Wednesday will see Indiana cool off after the warmer temperatures seen on Tuesday, as the warm air advection is forecast to temporarily weaken due to a more zonal temperature pattern and winds shifting to a more northwesterly flow. This wind shift will be associated with with a weak shortwave trough that will move through the state, which also has the potential to bring some light precipitation in the form of snow to the northern half of Indiana.

Thursday will feature the return of strong warm air advection, as strong winds are forecast to come out of the southwest bringing the warmest temperatures of 2014 to Indiana. This warm air advection will be the result of Indiana being on the leading edge of a sharp trough that is forecast to move through the state on Thursday. With this trough will also come some moderate precipitation, in the form of rain, across the entire state. The lift required for this precipitation event is forecast to come from strong PVA in association with a jetstreak moving just to the south of Indiana. There is also a chance to get some backend snow for this storm as cold air advection comes in behind the front.

Looking past Thursday, temperatures are once again forecast to be below freezing as winds out of the northwest will bring consistent moderate cold air advection to the region.
