A Stormy Stretch To Bring Needed Rain To SE WI
After a hot and humid weekend featuring highs in the upper 80's and low 90's, several rounds of rain are possible for the start of the work week. A broad sweeping cold front to our northwest this morning will slowly slide across Southeast Wisconsin by this evening.
This front will then stall overhead through Tuesday night and help trigger occasional showers and thunderstorms. There's a slight chance a few of these storms could turn severe with high winds and heavy rain. The time frame for the heaviest rain appears to be late Tuesday night and into Wednesday morning. Several computer models are generating 1-3\" of rainfall across southeast Wisconsin including our in-house high resolution model. The image below shows a running rainfall total from Monday through Wednesday morning.
If this rain verifies, it will go a long way to to reviving our thirsty lawns and gardens. Our rainfall deficit for the summer now stands at almost 4.0\" (3.95\"). A storm system moving from Colorado to Minnesota will finally kick this cold front through the area and sweep in cooler, drier air by Wednesday afternoon.
