(OLNEY/NEWTON) As a weak cold front moves off to our east this morning, a developing low level jet system moves over our downstate area, resulting in a very windy day for this Tuesday. Therefore, a Wind Advisory has been issued for all of Southeastern and South Central Illinois with the strong west / northwest wind anywhere from 20 to 30 miles-per-hour with gusts up to near 40 miles-per-hour possible. However, our sky will be mostly clear with plenty of sunshine, maybe mixed in with a few clouds, with temperatures expected to drop a little this afternoon back into the mid to upper 40’s. Wednesday and Thursday will be our coldest days of the week as a cold Canadian high pressure settles over the Midwest. The next low pressure system will develop across the Southern Plains on Friday and is expected to pass to the south of Illinois later Friday night into Saturday. Our downstate area could get some snow out of this weather system, although no significant amounts are anticipated at this time. Sunday and Monday will return to near normal conditions. Stay tuned for updates and monitor a NOAA Weather Alert Radio for more weather information and/0r details.
