March 15th, 2009 by Steven DiMartino

10:16 AM
Spring will officially begin on March 20th according to the calendar. Looks like the upper level pattern is going to actually help out in bringing Spring-like conditions to the forecast area. While the northern branch continues to sway between a negative NAO to a negative EPO pattern, the influence of the northern branch will [...]

A Return To Normal Temperatures Next Week

March 13th, 2009 by Steven DiMartino

6:06 AM
The cold conditions of this weekend will be a bitter memory by the middle of next week. The negative NAO that supported the strong high pressure system over the forecast area and the cold Polar air mass, will weaken and retreat to the north for next week. A more zonal pattern will unfold over [...]

High Pressure Keeps Storms At Bay Through The Weekend

March 12th, 2009 by Steven DiMartino

7:34 AM
There is a lot of moisture pooling over the southern Mississippi Valley this morning along the stalled cold front that blew through last night. The good news is that the high pressure system over the western Great Lakes is strong enough to keep much of that moisture to the south of the forecast area [...]

The Negative NAO Comes And Goes

March 10th, 2009 by Steven DiMartino

6:19 AM
In a span of roughly four days, the influences of the negative NAO will peak and fade over the forecast area as the Pacific jet stream begins to flex it’s own muscles.
Strong high pressure will dominate the forecast area on Friday through Sunday with clear skies and below normal temperatures. A cool Canadian [...]

March Madness Begins

March 8th, 2009 by Steven DiMartino

9:11 AM
March madness is about to begin for the forecast area. Well, really it’s already started. So far this March we’ve had a snow storm that produced more snow for some locations than what we received for December, January, and February combined; we’ve had mid 60’s for highs, and now an eventual return to cold [...]

And In This Corner!

March 7th, 2009 by Steven DiMartino

7:57 AM
A battle is setting up of atmospheric proportions between the more progressive Pacific pattern that is being established over much of the CONUS and a very strong negative NAO that is forming over the north Atlantic. For the most part, aside from the negative NAO, there isn’t much in the way of blocking over [...]
