40 deg. Temperature Drop for Deep South

March 4th, 2015 by Roy W. Spencer, Ph. D.

A strong cold front is forming today and will plunge through the Deep South, bringing a 40 deg. F temperature drop.

Here’s a time lapse video of hourly temperature forecasts from the WRF high resolution model, showing just how abrupt the temperature change will be as the front passes (original graphics from Weatherbell.com):

Winter storm warnings have been issued for northern portions of the South where up to a foot of snow is expected, mainly through the Ohio River Valley:

    What, weather again! Didn’t we have some yesterday?

    For an observer, and consumer of weather, it is almost, but not quite, amusing to see how weather has become a partisan issue.

    For those, like Dr. Spencer, who are directly involved in the arguments, I don’t expect it is amusing at all.

    When you give your temperature update, is there any significance to what average baseline you choose to compare it to?

    Also on those updates, when you write +.25 degrees for a zone and then it is +.25 degrees the next month, doesn’t that mean there was “no change”? People like me see all the (+) signs and think, “boy, the earth is really been warming.”

    Since it is only a mile away, I like when you talk about Lake Superior.

    I’m learning from other websites just how hated you really are by the man-made CO2 induced global warming crowd. Keep up the good work.

    Meanwhile, in other news, the start of the Iditarod Race has been moved due to snow accumulation in Alaska about 1/3 of normal, during a winter with an average temperature departure of +6 – +8 deg, depending on location. Also, ice fishing tournaments in Wyoming last month were cancelled because of dangerous ice conditions due to the unusually warm winter.

    While land surface temperatures over about 5% of the globe were below average over the last 30 days, about 20% of the globe was above average (via “eyeball integration” of the latest NCEP operational data global 30-day anomaly map).
