Over the general lower Great Lakes region, there could be a widespread weak capping inversion, which would likely be crushed by at least 3000 j/kg of instability currently being projected by the NAM. The Storm Prediction Center does mention the potential for 4000-5000 j/kg of instability, which is indeed very high. AND MLCAPE WILL LIKELY EXCEED 6000 J/KG WITH ADDITIONAL DAYTIME HEATING BY EARLY-MID AFTERNOON. This will be followed by rain showers and much colder temperatures Wednesday along with the occasional morning snow shower. A huge menacing cloud , swollen and black, suddenly releases a torrent of rain. Some of the low clouds and rain impacting much of Vermont Tuesday morning will give way a few breaks of sun and very mild weather as strong southerly winds blow the hint of seasonal change to MRG. Snow remains a possibility however and could arrive as early as Friday and continue into the night before either tapering off Saturday or turning to drizzle or a light rain. If we see a persistance of this body of below normal waters, or even an expansion, the possibility of a developing La Nina must be accounted for.

This factor doesn’t constitute an oscillation or index, per se, but will likely play into what we see happen this winter. This way the water won’t move your poles for the net and you’ll be able to play for as long as you want. Rock out your climbing workouts in a way Kurt Cobain would have approved. Since, covering them all is out of scope of this article, what we have here a simple outline of what most seasonal forecasting techniques involve. This is due again to our upper air setup which includes a ridge out west and a stubborn trough that wants to hold over the east. However, lagged effects often offset original effects, so that weather’s influence tends to wash out at a quarterly frequency. Fire history and effects are described for grassland and shrubland ecosystems, and the range of forested communities by plant series: Ponderosa Pine, Douglas-fir/White fir/Grand fir, Lodgepole pine, Western hemlock/Western redcedar, and subalpine fir/Mountain hemlock.

The Storm Prediction Center’s long range outlook for Tuesday places a 30% chance of severe weather within 25 miles of a given point across northern Texas, much of central and eastern Oklahoma, and southern Kansas. A 15% chance of severe weather within 25 miles of a given point is situated from central Texas north into Oklahoma (outside of the panhandle), much of central and eastern Kansas, and extreme western portions of Missouri and Arkansas. This spring we are anticipating a late end to winter in the North Plains and Great Lakes region. A potentially significant severe weather event continues to show up in model guidance for Tuesday, April 26th over the Central and Southern Plains. The NAO, which has a tendency to provide us with the more favorable storm tracks continues to be negative and favorable. There continues to be a big compition between the teleconnection indicators as we head toward next week regarding the prevailing weather pattern.

The heat then breaks towards the end of the week as unsettled weather enters our area Wed night. If we see the red over Greenland and the blue near coordinates 50/50 then we might have a situation where cold air is locked in place along east coast and sub tropical moisture gets thrown into it. This is so very true for Majorca Weather, which gets little cold due to mountains that are also part of the island. The string of below normal water temperatures is not extremely significant, and many of those little below-normal anomalies on this ‘string’ are only slightly below normal. Once the system clears during the weekend, the return of sunshine will mean that afternoon temperatures climb to well above freezing over a succession of days beginning Sunday and persisting through next week. This will change as we approach monday however as that trough I mentioned makes a return as seen below by the deep blue colors..
