After this weak system moves eastward, model guidance sees another small storm system dropping into the Midwest, likely laying down some low-accumulation snows. 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. Abstract : The report examines in detail the weather conditions over Nigeria during five typical positions of the surface discontinuity between Saharan and Atlantic air. This surface low in the southeast was expected to move innocently out over the Atlantic leaving the second piece of energy to get torn to pieces by what appeared to be the prevailing influence of the polar jet. Consumers go for energy-efficient dishwashers because they can cut the overall cost of energy consumption. If you look closely, you can see the pulse of warm temperature anomalies suddenly flare up over the Himalayan mountains, a sign of possibly sudden strengthening of this warming mass.

Analyzing the above animation shows us that this warming event has been in the works since the beginning of February. As I alluded to in my February 24th post, the Himalayan mountain range is a natural geographic instigator for these sudden stratospheric warmings. In my opinion, if you see a warming event over the Himalaya Mountains and it is sustained and strengthening, there’s a solid chance that a sudden stratospheric warming could emerge from that situation. This body of upper stratospheric warmth may very well be in its final stages of formation and the beginning stages of possible propagation to the Arctic, where the sudden stratospheric warming event could then take place. The enormous warming event we saw in January originated from the same mountain range we are now seeing this impending mass of warmth. And no, this bad pattern is not due to global warming. The bad news is relegated to the distant future where ensembles show a trend toward milder temperatures beginning around the 20th of the month.

What can be done in the future to address future risks? Informed consent encompasses explanation and discussion of the purpose of the screening tests, potential advantages, the possible risks to health, as well as the limitations of any particular genetic testing procedure. Overview: Weather & Radar Pro gives forecasts for any location, as well as radar images showing rain, cloud, thunderstorms and temperatures. Shown above and below are several radar images (all from around 6:40 am MST). Shown above is an animation of 10 millibar temperature anomalies in the stratosphere. These east winds are forecast to occur Thursday night into Friday morning, putting the Tucson metro area back onto the temperature roller-coaster. On the back of this aforementioned good news is a promising forecast for the weekend. The good news involves the weekend. The last weekend in February into the following week looks extremely changeable. Cold weather should dominate for much of the weekend but it will be temporary in nature.

We have managed to avoid that for much of the month believe it or not. 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. 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. With Thursday’s system, temperatures will again be close to freezing. If we don’t get precipitation to mix with sleet or freezing rain we could certainly see a few inches. Temperatures should sneak above freezing Tuesday afternoon and then hover around the freezing mark Tuesday night as light snow begins to fall. Clouds should make a return later Tuesday in advance of the first of these aforementioned weather systems. Whenever you are opting for a shed, you should first decide for what purpose you will be using them.
