27 degrees at MSP Airport this morning
25 degrees at Crystal Airport in New Hope!
9 degree dew point at Windom & Worthington this morning
36 degree dew point in Phoenix and Albuquerque this morning
Driest air mass in the USA over Minnesota today
Rain chances increase Thursday night & Friday
A few wet snowflakes possible in parts of MN next Tuesday?
The Weather Lab lilacs looked quite "droopy" this morning as temps dipped well below freezing again.
Temps bottomed out at 27 at MSP Airport, and 25 at Crystal and Blaine this morning.
That's a hard freeze in anybody's book, and may have damaged some of the more sensitive flowering plants like apple trees. I'll leave that report to the experts in the field.
Cold yes, and extremely dry too:
Welcome to the "Scandinavian Desert."
It's not unusual to get freezing temps this time of year, but this air mass is remarkably dry. A check of dew points this morning shows the air mass over Minnesota this morning is much drier than many cities in the desert southwest. In fact, the air mass over Minnesota is basically the driest in the nation (lower 48) today.
Location - Dew Point
Wothington, MN 9 degrees
Windom, MN 9 degrees
Hallock, MN 9 degrees
MSP Airport 17 degrees
Phoenix 36 degrees
Albuquerque 36 degrees
Las Vegas 31 degrees
Palm Springs 41 degrees (rain at LAX!)
Denver 46 degrees (fog!)
Rain by Friday?
It appears low pressure spinning in from the west will inject enough moisture into Minnesota Thursday night into Friday morning to give us a few much needed showers.
The NAM & GFS suggest a band of showers (and a rumble of thunder?) late Thursday night into Friday morning.
Overall rainfall totals look light to moderate, with somewhere between .20" and .40" the most likely scenario at this point. There is some indication the system could slow down and linger over Minnesota Friday morning, which might help boost rainfall totals.
S-N-O-W flakes next week?
A second system may push toward Minnesota by Monday and Tuesday.
The GFS (which has not performed terribly well as of late) tries to bring a mix of rain and a few wet snowflakes to Minnesota (mostly north of the metro) Monday & Tuesday. The European model suggests the system could steer south of Minnesota.
