You may have noticed an uptick in the humidity levels around the area as of late, and especially yesterday as we achieved the warmest high temperature of 2015 so far as our high topped out at 92 degrees. The humidity along with a warm front moving through the area later today will set the stage for some active thunderstorms starting later this morning and then later this afternoon and evening. The Storm Prediction Center has the area outlined in a slight risk of severe weather, with large hail and damaging winds possible as the storms develop and move through the area. An isolated tornado can't be ruled out as well since the warm front will be in play, but the greater risk for that appears to be out west near an area of low pressure that will be moving into NW Iowa. Highs today will remain quite mild, in the middle to upper 80s with plenty of humidity to go along with it.
Tonight a thunderstorm complex will develop out to the west and move through the area, with the threat for large hail and damaging winds still persisting.
For Friday, we may see some scattered shower and thunderstorm activity in the morning, and then again in the afternoon as a front sweeps across the area. The whole day won't be wet though, there will be some dry hours. Highs will be near 80.
Relay for Life of Whitside County is being held this weekend and so far it's looking dry and actually pretty pleasant. High pressure will be in control leading to sunny skies and cooler temperatures!
Rain chances will return once we hit Sunday and continuing into the first part of next week.
Have a great Thursday!
[FB: Another warm and humid day on tap for the Sauk Valley and with it will come increasing chances for some stronger storms as we head into the afternoon hours. An approaching warm front will help fuel the storms which may contain large hail, damaging winds and isolated tornadoes. Temperatures will be in the middle to upper 80s this afternoon with heat indexes in the 90s.
Tonight a storm complex may develop out to the west and then move in later this evening. If it can maintain itself, the main risk from this line will be damaging winds.
We'll keep an eye on the radar throughout the afternoon and evening and pass along any watches/warnings that may be issued from the SPC and NWS.
Relay for Life of Whiteside County is actually looking very pleasant this upcoming Saturday, as high pressure will be briefly in control of our weather pattern giving us partly sunny skies and very comfortable temperatures. Highs will be around 80 with temperatures falling through the 70s as the event progresses. Definitely make sure and check it out if you can!]
