Through Thursday night…
The forecast in the short term remains relatively quiet thanks to a large area of surface high pressure that will drive most of our weather for the next couple of days. A tight pressure gradient ahead of the high pressure center has resulted in some breezy conditions this afternoon. This will only last into this evening before the pressure gradient weakens and we stop mixing into the enhanced flow aloft for the night. Mostly clear conditions will hold on through the night causing temperatures to cool to near or just above freezing for most by early Thursday morning with the help of some very light winds overnight. The clear skies and light winds are also expected to result in some areas of fog overnight. Guidance insists that the fog shouldn`t be widespread, yet models are having a hard time agreeing on where to place the most favorable areas for fog to develop. However, the RAP has liked the Illinois River valley all day long and the HRRR is trending toward the same idea.
Heading into Thursday, we should begin the day with lots of blue sky. However, after the center of high pressure moves to our east Thursday morning, the return flow will introduce some mostly cloudy conditions for the latter half of the day. Despite the clouds, no rain is expected through the day on Thursday. Temperatures will be similar to today with highs in the mid-50`s. The added cloud cover is one factor that will keep temperatures a bit warmer Thursday night than tonight. Lows early Friday are forecast in the middle and upper 30`s.
