True Summer Week Ahead...

As the cold front that has lingered across the state the past couple of days finally moves to the east/south, we'll be left with more of a typical July week. Warm temperatures, increasing humidity, and some occasional pop-up thunderstorms will take hold through Friday and the next storm system.

Temperatures today should range from the mid to upper 80s throughout the state, with a little less humidity than the previous couple of days. Isolated thunderstorms are possible in extreme southern Iowa, as the cold front lingers there during the early afternoon hours. Tonights' lows should from the upper 50s to mid 60s from north to south across the state, and showers/thunderstorms should be focused in Missouri/Illinois.

Wednesdays' highs will be in the 80s throughout the state under partly cloudy skies, and increasing moisture. Currently the Sioux Falls NWS is hinting at some isolated thunderstorms that may be possible, mainly for northwest Iowa. Wednesday night lows in the lower to mid 60s throughout the state with a few of those isolated thunderstorms lingering in northwest Iowa for the early overnight. Thursday shows much the same, with highs in the mid and upper 80s, a few 90 readings also possible. Partly cloudy skies, and fairly humid conditions will give way to a fairly nice summer day, with those occasional pop-up thunderstorms once again possible across the northern third of the state. Thursday night lows in the mid 60s to near 70 from east to west across the state.

The end of the work week, and the next system approaching will give way to strong southerly winds pumping both heat and moisture into the state. Friday's highs will reach into the 90s throughout the state, mid 90s even along the Missouri River. Friday nights' lows will represent the increase in moisture, as they only fall into the mid 60s to lower 70s across the state. With the aid of a surface front, and its' features, will lead to thunderstorms possible across much of the state Friday evening through the overnight. These thunderstorms are expected to yield a potential severe weather threat where they do develop. More details on some of the pop-up thunderstorms, as well as Friday's severe weather threat will be available in later updates.
