Threat For Rain Goes Up at the End of the Weekend

The threat for rain remains minimal over the next couple of days. A long-wave trough over the Great Lakes will keep weak lift near by, and with weak energy passing through it, its possible for a few isolated showers this afternoon, and a very small chance for a shower on Friday. High pressure arrives on Saturday which will keep abundant sunshine in the forecast through the afternoon. However clouds will build late Saturday, turning mostly cloudy in the evening.

This incoming cloud cover is due a low pressure system that moves out of the Rockies and into the Southern Plains Friday to Saturday. Going into Sunday, the low then moves into southern Illinois and Indiana. This low will pull it's warm front north into central Illinois by Sunday afternoon, which develops scattered showers across northern Illinois. With this current forecast track, the heaviest rain and the most available moisture will be near the low. This will bring heavy rain, in excess of two inches, from eastern Oklahoma to Arkansas and far southern Illinois. Sitting to the north of the system, the rain we do get shouldn't add up to much. At this point we only look to get about .25" to .50" of rain Sunday. However, we keep small end chances for rain Monday through Wednesday.
