A New Week... New Thunderstorm Chances...

We begin the work week with something that not a lot of places need to see, thunderstorm chances. In fact, extreme northwestern Iowa is under a 'slight' risk for severe weather this evening and into the early nighttime hours. Threat for large hail and some damaging winds are the main threats as storms will fire along a cold front that is slowly moving southeastward.

This storm system is already responsible for some thunderstorm activity that is making its' way across northeastern and central Iowa this morning. Once those storms clear, expect the sun to shine and high temperatures warm up nicely with an increasing southerly wind over the state. Mid 80s for the northeastern part of the state where clouds will hang around for some of the day, otherwise upper 80s for central Iowa and low to mid 90s across the western third of the state. Thunderstorm chances tonight over northern Iowa; lows in the mid 60s to lower 70s across the state. Once again there is a chance that a few storms tonight could reach severe limits over extreme northwestern Iowa.

Thunderstorms chances should overtake much of the northwestern half of the state by Tuesday afternoon, with some potential for severe weather across the state as well. Details on the severe threat for tomorrow will be better defined and explained during tomorrow mornings' update. Highs in the upper 80s and lower 90s in the southeastern half of the state ahead of the cold front; while behind the front expect highs only in the upper 70s and lower 80s. By Tuesday night expect thunderstorms stretched across the state from LaCrosse, WI to Omaha, NE moving southeastward with the chance of a few severe thunderstorms and the possibility of more heavy rain over the state. Lows during the overnight will range from the lower 60s to lower 70s from northwest to southeast.

Rain/thunderstorm chances continue over the southeastern half of the state on Wednesday, mainly during the morning and early afternoon hours before exiting the state. Highs on Wednesday will be in the mid 70s to lower 80s from northwest to southeast once again as the state should be behind the cold front. Lows on Wednesday night in the mid 50s to lower 60s as well, making for a near chilly night.
