Bow echo & MCS roll on:
The large and powerful storm that rolled through Minnesota Sunday evening is called an MCS, or mesoscale convective system. These systems have wider coverage and longer lives that your average batch of thunderstorms, and can travel for hundreds of miles and last for days.
Note the system this morning as it continues to produce damaging winds and severe T-Storms warnings as it races through Madison and Chicago.
Severe storms rumble into Chicago Monday morning.
Free A/C through Wednesday:
The cool front responsible for triggering Sunday's storms is pumping in fresher and cooler Canadian air into Minnesota.
GOES 1km visible satellite shows clouds pushing south of Minnesota. Yellow "streamlines" depict wind flow, with drier air pushing in.
Dew points behind the front are falling into the comfy 50s, and we'll feel that drier air as the day wears on. There will be about half as much moisture in the air by late today compared to (70s dew points) Sunday.
The transfusion of cooler direr more breathable air will last through Wednesday.
Summer 2011: Hot so far:
Friday is July 15th, and that means roughly we're at the halfway point of meteorological summer Friday!
So far summer 2011 is running significantly warmer than average.
+1.1 degrees in June in the metro
+6.6 degrees in July so far
92 degrees Sunday at MSP Airport
8 days at or above 90 degree days so far
13 the average # of days at or above 90 in the Twin Cities each summer
Heat returns by Friday:
After the pleasantly cooler & drier respite from heat & humidity this week, a big ridge of high pressure will build north again into Minnesota by Friday.
Look for temps to soar back well into the 90s, and dew points to surge into the tropical 70s again by the weekend.
The GFS model is hinting that the large ridge of high pressure in the upper atmosphere may be a semi permanent feature through the rest of July. Translation? It's going to be hot & humid for most of the rest of the month.
After a reluctantly cool spring, it's a real summer in Minnesota this year!
