Cool to Rule 1st Half of October

This is a very quick post (since I am under the wx) to update everyone as to the potency of the cold air masses that will invade the eastern part of North America over the next 2 weeks.  First, I will show you maps of temperature normalized anomalies in DEGREES FAHRENHEIT  for the next week at different days...so here goes...first for Sunday...quite chilly with snow falling or have fallen over the mtns of PA to the tune of a couple of inches on the highest ground...

Then this upcoming Thursday...the purplish color is ~15-20ºF below the norms...

How about next Saturday...if this verifies, it will be max temps in the mid 40s for us near KMDT!

Now...in degrees Celsius...the average of the next 8 days...(Remember the are 1.8 degrees F for every 1.0 C...so basically look at the scale and double it for the F equivalent...its a good guesstimate...sort of...).

And then for the 2nd week or days 8-16...

When you take all 16 days coming up according to the modeling and average the temperature anomalies, it looks something like this...that is one cold month of October east of the Rockies!

OK...and if the early season chill is not enough for y'all, check out this you tube video for a taste of the properties of this air mass moving south and east!

And enjoy the Cool Columbus Day weekend...Sunday will be raw...will not make it to 50ºF!
