Warmer, more unsettled days ahead in an active weather pattern

May 13, 2015 0 Comments

After a blustery, raw start to the week, things have momentarily brightened up and gotten much more pleasant for us thanks to an area of high pressure. This at least gives us a break from clouds and showers for a day in what is shaping up to be a long-term “active” weather pattern, one that is bringing frequent doses of rain and thunderstorms to the Upper Midwest.

A southwesterly flow aloft means warm, but unsettled stretches of weather for the Upper Midwest. Showers will be possible Thursday and for parts of the weekend.

Right now, a southwesterly flow pattern has developed with a large area of low pressure in the desert southwest feeding energy along the jet stream aloft toward our area. One area of low pressure will pick up plenty of moisture as it moves in for Thursday, bringing as much as three-quarters of an inch of rainfall to our weather picture.

A ripple of energy associated with a surface low pressure system will produce a few waves of showers and thunderstorms through the weekend. Warmer, moister air will set the stage for some strong activity.

A surface low pressure system will produce scattered showers and thunderstorms for Friday night and for parts of Saturday, especially later in the day toward the evening. High temperatures will be in the 70s to near 80 on Saturday afternoon with noticeably higher humidity content in the air priming the atmosphere for more shower chances. Severe weather¬†will be possible Saturday night with large hail and damaging winds developing to the west and rumbling to the area in a complex of activity.¬† Another round may be possible Sunday as the cold front associated with that storm system approaches from the west. The best chance appears to be in the afternoon and evening if this in fact does erupt locally. Our chances of severe weather depend on the cloud debris and remnant shower activity from Saturday night’s storms. The Storm Prediction Center has placed parts of the Midwest in the Slight Risk of severe weather for the weekend.

After the weekend wave moves through, high pressure will bring quiet weather for the first part of next week before yet another low pressure system develops, bringing rain chances for the second half of the next week.

Another storm system may bring shower and possibly thunderstorms chances for the second half of next week while temperature in the longer term through next week leading up to Memorial Day weekend look to be near seasonably mild with 60s to low 70s possible.
