Severe Weather Possible

Severe weather is in the forecast for the state this evening and tonight, as well as tomorrow, Monday and possibly Tuesday once again. For this evening, thunderstorms developing near a warm front that is draped across the state may become severe with damaging winds, large hail and isolated tornadoes. A Tornado Watch has been issued for portions of northwest Iowa until 1 AM due to this risk. Additional watches may be issue for the rest of western & central Iowa as the risk expands overnight. Lows overnight tonight should be in the 60s throughout the state; with lower temperatures expected in northeast Iowa and the warmer temperatures in southwest Iowa.

Tomorrow will see the storm system continue to stay in the vicinity of the state, putting most of the state under a severe risk area. Thunderstorms should be ongoing at the beginning of the day, with some clearing taking place during the afternoon. High temperatures in the low to mid 80s across the state; Lows in the mid 60s to lower 70s. The severe risk will be defined on how much sunshine the state receives and how much moisture continues into the state; more details in later updates are possible.

Another day with a severe risk for a majority of the state on Monday; with a weak 'warm' or stationary front over the state and a cold front off to the west. Severe weather seems to likely be in a damaging wind threat as storms fire off of the cold front and sweep across the state in the form of an MCS. Highs during the day in the upper 70s or lower 80s in northeast Iowa with temperatures rising into the lower 90s possibly in southwest Iowa. Lows overnight in the upper 60s to lower 70s from north so south...

Tuesday may see somewhat of a severe threat ahead of the cold front that will move across portions of northern Iowa. The extended severe outlook does have a portion of northern Iowa included. Despite the severe weather threat, highs for the day will be quite warm; mid 80s in the northern third with lower 90s and maybe even a mid 90 temperature in the southern third. Lows will be dramatic across the state with the cold front influencing temperatures; lower 60s in northwest Iowa to lower 70s in southeast Iowa.

Continued severe weather updates are possible throughout the next couple of days.
