High temperatures have started moving upward today and will continue to do so through the end of the week. Under plenty of sunshine with breezes from the southwest, highs will range from the low 30s over eastern parts of central Iowa to the low 40s over western parts of central Iowa on Thursday. Even warmer air is expected on Friday with highs in the 40s over most of central Iowa and it’s possible a few places in the southwest or western part of the state will reach the 50s. Temperatures will remain above normal on Saturday with highs in the upper 30s to middle 40s. A winter storm will move into and through the region early Sunday into Monday. Rain and snow will transition to all snow Sunday night into Monday morning as winds turn gusty and bring cooler air into the state. The best chance for accumulating snow will be over the northwestern part of the state. However, it remains too early to state snow amounts and locations of the heaviest snow as that will be dependent on the exact storm track. Continue to monitor the forecast for further updates.
A potent low pressure system is slated to trek across Iowa later Sunday into Monday that will bring snow and tricky travel conditions to parts of the state. Where exactly? Well, some uncertainty remains in the track of the system, but the northwest third of the state looks to have the best opportunity for accumulating snowfall at this point. Other areas will want to monitor subsequent forecasts as a small shift in the track can have big ramifications for where it will snow or where it may just be rain. Stay tuned!
