Chilly & Dry, Some Warming Easing In....

Good evening.  What a difference a few days can make!  We were basking in unseasonably warm temperatures with nighttime lows that dropped only into the 50's a few days ago, now we are back into more seasonable weather and chilly conditions.  Let's take a look and see what we have under the hood:

SUMMARY:  Canadian high pressure is in firm control of our weather for the next several days, limiting precipitation chances to basically slim and nil.  Computer forecast models suggest the next good chance at some precip doesn't occur until near the middle of next week, and that looks like it will be a rain event at this point, time will tell.  Another Nor'Easter is a possibility, as models have a storm off the New England coast a week from today.  Temperatures here do start moderating, with some upward mobility culminating with a shot at 50 for the weekend.

PRECIPITATION:  As I stated above, there's not much of anything to work with as far as precipitation for the next several days as fairly dry Canadian air gets a firm foothold over the area.  Upper level patterns keep the flow northwesterly, even though we'll see some southerly winds near the surface, so you don't get a lot of moisture in here to trigger rain or snow and such.  This time of year there generally isn't much instability to kick off rain, cold air likes to sink and is generally stable by nature.  Take a look at the National Weather Service forecast for the next five days:

5 Day Precipitation Forecast
BONE DRY in this neck of the woods, which is good.  No snow to mention.  Looks a like a boring, benign pattern shaping up for us.

SEVERE WEATHER:  Nothing on tap for the next three days anywhere in the US according to the Storm Prediction Center.  Just a general risk for garden-variety thunderstorms in South Texas tomorrow and in the Southeast on Thursday.

All quiet on the Grand Rapids NEXRAD radar and some lingering cloud cover is slowly exiting the area.  Take a look at the temperatures around the area right now (7 PM EST)...


Just a couple of days ago there was a 70 on this map.  Geez.

Here's the forecast for Jackson and vicinity:

Tonight, slowly clearing skies, chilly, lows near 25, winds S calm to 5 MPH.

Wednesday, a little mixed sunshine, warmer, high 42, winds S 4-8 MPH.

Wednesday night, periods of clouds and stars, chilly again, lows near 27, winds S 3-6 MPH.

Thursday, some clearing to mainly sunny skies with perhaps a few clouds and a high near 47. Winds SW turning ESE 3-6 MPH.

That should set you up for the next couple of days, we'll have more for you later!  Blessings.
