Summer Cameo...Then The Bottom Falls Out

Good Morning!

Spring and Summer still think they're supposed to be around here with temperatures that are 20 degrees above normal with southerly winds and fair skies.  Don't get too used to it though, because when it goes away, it GOES.  We'll give back every bit of that 20 degrees above normal and then some, as temperatures struggle to reach 50 late this weekend.  Let's take a deeper dive and see what we have going on here...

SUMMARY:  A ridge of high pressure is sitting over the eastern half of the US today, with warm southwesterly flow under it, and I mean REALLY southwesterly.  Warm air is having to dip far into the Desert Southwest to get around the trough that is firmly locked in over the western part of the nation, and by tomorrow, as the trough starts moving this way, that warm air has to go into Mexico and then work back in through Texas and the Gulf Coast.  Temperatures do the mid 70's bit today and tomorrow, then the nosedive begins.  By Saturday, the cold front breezes in, winds become northwesterly, and we see daytime readings hovering in the mid to upper 40's, with some chances at a rain/snow mix on the table.  Yes I said it...SNOW.  While you're relishing the unseasonably warm weather today, remember that the normal high in this part of the world is right around 54 degrees.

PRECIPITATION:  Let's get right to what the National Weather Service thinks regarding precipitation totals for the next five days.  Here's their forecast map, valid thru 8 AM Monday:


Most areas in this part of Michigan come in right around an inch.  That will happen as the cold front gets here  Friday and Saturday with the trough pushing down from Canada.  Forecast modeling is suggesting that a major low pressure system develops over New England and the Appalachians, and moves east, we pick up rain from the northeast on the back side of it.  A full blown Nor'Easter?  Maybe.  One other thing that big-time low does is steer Tropical Storm Sandy away from New England.  If this forecast setup holds, Sandy moves due north until she gets offshore a ways from North Carolina, then she goes northwest and heads out to sea.

TROPICAL STORM SANDY:  Currently she is south of Jamaica with sustained winds of 70 MPH, and tracking due north at 14 MPH.  The only reason I mention her is that she may have some say-so in the precipitation picture this weekend and early next week.  For now, she has to get through Jamaica, Cuba, and the Bahamas.  We'll see what she does over the next few days.

SEVERE WEATHER:  Nothing directly impacting the blog area the next three days.  The Storm Prediction Center is suggesting a slight risk of severe weather for the Upper Midwest, Wisconsin and the Upper Peninsula of Michigan primarily for today, due to a cold front that is expected to move into that area late this evening and tonight.

We're mild already, all reporting stations in the mid 60's at this time, and the temperatures are only heading up from here:

And here's your forecast for Jackson and surrounding areas including Rives Junction and Concord:

Today, mainly sunny skies, perhaps a couple of passing clouds, unseasonably warm with a high of 75, winds SSW 5-8 MPH.

Tonight, mostly moonlit skies, again a few clouds may float by, nighttime lows only roll back to 56, winds SSW 5-8 MPH.

Thursday, continued sunny, breezy, warm, and wonderful, high 75, winds SW 10-15 MPH.

Thursday night, skies become cloudy with a chance at scattered showers and possibly a storm, temperatures fall sharply, lows drop to 45 with winds turning NW and increasing to 20-30 MPH with gusts to 40 possible.

Friday, cloudy skies, showers and maybe an isolated storm likely during the afternoon, much cooler than Thursday, daytime highs only reach 52.

Saturday, cloudy skies, cooler still, rain showers likely, high only 47.

Sunday, continued cloudy and cold, chance of rain, possibly a few flakes mixed in, high 45.

Monday, slowly clearing skies, cool, high only 47.

Tuesday, clear skies, high 48.

There's a look at your forecast for the next six days, I do hope that you have a great day!  Blessings.
