THE TORNADO. TAKE COVER NOW. In 1999 I purchased a box of Wheaties with Muhammad Ali on the cover. Since the two types of air have different densities and temperatures, they also cannot mix. Two days where no longer do we expect above-freezing temperatures and where significant additions can be made to the base. With the right experts of negative energies remedial you can achieve peace and harmony in life. The warm air in the stratosphere would then push cold air down to the surface, and we could see that cold air hit the surface in the next 2-5 weeks, right around the start of severe weather season. It actually caught me a bit by surprise to see what appears to be a major and widespread shot of arctic cold interrupting a mediocre pattern. This should also be temporary but it result in a bit of rain. However it seems more likely that the weather will become more changeable again with near normal temperatures, particularly in the north and west, with more spells of rain and strong winds.

In short, higher instability means that the air is more buoyant- it is able to rise easier, and thus create thunderstorms. The jet is also causing Pacific air to run much of the eastern part of the country over, thus the mild weather. These disturbances in the jet stream look like Alberta Clippers but they are getting propelled by the strong Gulf of Alaska ridge and intense jet in the eastern Pacific. All models I observed for December 2013 depicted a tightening of the contour lines and lowering of height anomalies in East Asia, sometimes even into the northern Pacific. If you look closely, you’ll also see an area of divergence, where the contour lines seem to bulge away from southern Wisconsin and northern Illinois. It is expected that the broad area of low pressure will meander its way northward as the day progresses, bringing the warm sector further north as well.

On the evening of April 9th, we see a broad sector of elevated instability on the order of 2000 to 3000 joules per kilogram extending from Iowa to southern Texas. Higher instability values are found in Texas and Oklahoma, where the dry line is expected to produce more instability-based storms than those further to the north. We also see a broad area of low pressure centered in Kansas, with a warm front draped across Missouri, a trough along the Oklahoma/Arkansas border, and a dry line in western Oklahoma and central Texas. Temps will chill, slowly at first but as the night wears on, much chillier temperatures build into the area. 9. Language differences will disappear: Nostradamus wrote that because of a new motor, the world will return to being as it was during the days of the Tower of Babel. The sun is expected to return in the afternoon when the mercury will top out near 42 degrees. Clouds should make a return later Tuesday in advance of the first of these aforementioned weather systems.

Temperatures should sneak above freezing Tuesday afternoon and then hover around the freezing mark Tuesday night as light snow begins to fall. With Thursday’s system, temperatures will again be close to freezing. If this cold air is able to come close to the US, or even penetrate through the nation, chances are the severe weather risk and winter weather risk would be heightened. It will not have a lot of moisture or cold air to work with but the push of mild weather also appears weaker than I had feared. Cold weather should dominate for much of the weekend but it will be temporary in nature. In addition, there is a risk for more significant severe weather. After a brief dry period later Wednesday, another system, with a little more moisture should bring what looks to be snow but possibly mixed precipitation to the region Thursday. There is little precipitation currently, except far to the north over higher elevations. Above is a base scan (0.5 degree tilt) from the PHX NWS radar that indicates some light precipitation over higher elevations to its northwest; substantial ground clutter noise over metro Phoenix; and little to the south. It will be another instance where wet snow falls over the low elevations while we get a more powdery accumulation near the summits.
