It’s been an active past few days with severe weather across the South up through the TN/OH Valleys and while the South and southern Mid-Atlantic roasted, a heavy late season snowstorm impacted the Upper Midwest with 6-12 inches of snow from Iowa to the UP of Michigan.
Here’s the latest US snow cover. Currently 28.3%.
Close up of the North-Central region. A decent snow cover for the Dakotas into Minnesota and northern Wisconsin following the two heavy snowfalls to start and end this week.
Check out these web cams images just after sunset. That’s a pretty decent snow cover for April 4.

Here was the highs today across the US. Big temperature difference not only between the Northern Plains and Southeast but even between Richmond, VA (85), Washington DC (63) and New York’s LaGuardia (47).
It was warmer yesterday from Alabama to North Carolina where highs were widely into the low to upper 80s. Warmest of the year so far.
Beneath clear skies and with fresh snow cover across Minnesota, Wisconsin and the UP of Michigan, it will be a chilly night with lows dipping widely into the teens with some single digits. The chill even sees cities such as KC and St Louis down to freezing tonight, 20s in the burbs.
The still chilly air over the Great Lakes has ice cover at 63.7%. That’s still above normal for the peak time of year and 900% above normal for early April!
Here was the severe weather reports from yesterday.
Today also saw it’s share of severe weather.
Super Weekend Coming Up
With no storms and a lot of sun and high pressure, temperatures are looking perfect this weekend. A great one for outdoor activity.

Looking ahead to next week and we have another big storm system. A system which not only presents a severe weather threat but a widespread heavy rain and flood threat for the East. Check out the 7 day QPF. Notice though the the heaviest precip appears to stay just offshore once your north of NC. That’s a lot of water from Southeast up the coast.
Here’s the GFS showing that next system gathering initially over Texas, bringing big rains across the South.
On the backside of this system we see another punch of chilly air which may present a freeze threat deep into the TN Valley. Note the significant warming Out West.
850 temps next Wed.
It looks like a fairly quiet pattern beyond the heavy rains of early next week.
Could Recent Tsunami Wave Action Have Had A Cooling Effect On Equatorial Pacific, Slowing Onset Of El Nino?
I made mention on twitter a few days back about the potential upwelling and consequent cooling over the eastern equatorial Pacific in response to the recent tsunami waves generated by the two major Chilean earthquakes. There was at least two major quakes. 8.2 followed a day later by a 7.8. Keep in mind that these would have significantly stirred the ocean from below.
Probably wouldn’t have the power to affect SST’s over a long period of time and enough to halt, but perhaps slow down the onset of El Nino?
Check out the global SST anomalies as of April 3rd. Note the squiggly ‘cold anomaly’. Perhaps I am barking up the wrong tree.
More tomorrow!
