Low pressure is intensifying near the Mid-Atlantic coastline this morning and it will keep it breezy and quite cool around here through tonight with periods of rain. This system will push away on Thursday, but a cold front will approach and then stall in the area for the late week. There can be a few showers from Thursday into Friday and then a period of steadier (and more beneficial) rain is likely from late Friday into Saturday as low pressure forms along the stalling-out frontal boundary zone. Temperatures will be well below-normal today with an ocean flow of air and will remain slightly below-normal right into the weekend. The pattern looks like it’ll turn warmer and drier as we transition to the beginning of June on Sunday and into early next week.

Recent rain events in the Mid-Atlantic region have helped to alleviate drought conditions that began to develop last fall and more beneficial rainfall is on the way with two storm systems. Clouds will lower and thicken today as high pressure shifts off to the east of here and low pressure pushes into the Ohio Valley. A new low pressure system will form by early tomorrow near the Mid-Atlantic coastline and it will produce periods of rain for the mid-week and quite cool conditions as a low-level ocean flow of air forms in the DC-to-Philly-to-NYC corridor. In fact, temperatures may end up being some twenty degrees below-normal on Wednesday with the influence of the still chilly western Atlantic Ocean. A cold front then pushes through the region on Thursday night with a few showers and stalls in the area on Friday. Another low pressure system will likely ride up along that stalled-out boundary zone potentially bringing another round of soaking and beneficial rainfall to the Mid-Atlantic region from late Friday into Saturday.

Lots of patchy fog around this morning and then partial sunshine should return in the afternoon with the chance of PM showers and thunderstorms. It turns warmer during the next few days and the warming trend accelerates late in the week and this weekend with upper 80’s possible for afternoon highs.

More beneficial rainfall is headed to the Mid-Atlantic region…high pressure shifts to our east today and low pressure will make a move up the Ohio River Valley and then a new low pressure system will form near the Mid-Atlantic coastline. As a result, rain can push into the area by early tomorrow and the mid-week will feature periods of rain and quite cool conditions as the result of an ocean flow of air. A cold front can produce more shower activity in the region later in the week and even a period of steadier rain is possible from later Friday into Saturday. Temperatures will be well below-normal for the next couple of days for the latter part of May and remain a bit below-normal as we head into the weekend.

It was during the height of the Cold War and a powerful solar storm could have led to a disastrous military conflict between the US and Soviet Union if not for the early efforts of the US Air Force to monitor solar activity. On May 23rd, 1967, a solar storm took place that was so powerful, it jammed radar and radio communications in polar regions and the US Air Force actually began to prepare aircraft for war thinking the nation’s surveillance radars were being jammed by the Soviet Union. Fortunately, space weather forecasters in the military suspected there might be another cause and they relayed information about the possibility that a solar storm could have been the reason for the disrupted radar and radio communications. As it turned out, this information was enough to keep the planes on the ground and the US avoided a potential nuclear weapon exchange with the Soviet Union.

While global sea surface temperatures continue to run at above-normal levels, there has been a rather dramatic cooling trend across tropical regions all around the world. During the past year or so, water temperatures in the Indian Ocean have dropped to nearly neutral levels around India and well above-normal levels immediately east of Africa have moderated to only slightly above-normal conditions. In the central part of the tropical Pacific Ocean, relatively neutral water temperatures have replaced the El Nino conditions of a year ago when water temperatures were as much as two degrees higher than normal. Perhaps the most dramatic change in water temperatures has taken place in the tropical Atlantic Ocean where much warmer-than-normal conditions of a year ago are virtually normal as we approach the end of April and there is even a pocket of colder-than-normal water just off Africa’s west coast. The tropics are a critically important part of the world with respect to the total energy budget and cooling trends can certainly have an inhibiting impact on the upcoming tropical season.

The summer season is fast approaching, and probabilities are high that overall temperatures in the Arctic region will be nearly normal which happens to be right around the 32 degree (F) freezing mark. Chances are indeed high since this temperature pattern of nearly normal conditions during the summer months of June, July, and August has taken place virtually every year since the turn of the century. Meanwhile, the other nine months of the year in the Arctic region have featured above-normal temperatures in a pattern that too has also been very consistent in recent years.
It is the temperatures in the summer months of June, July, and August, however, which are the most important when it comes to Arctic sea ice extent as this is the melting season up in that part of the world. Arctic sea ice extent has been running at below-normal levels since the middle 1990’s; however, if temperatures again remain nearly normal during the summer (melting) season, the chance for any additional significant drop off will be limited. Indeed, given this consistent summertime temperature trend in recent years, Arctic sea ice has shown resiliency both in terms extent and in volume. One possible explanation of this persistent temperature pattern across the Arctic region featuring nearly normal summertime conditions and warmer-than-normal during the coldest nine months of the year is the increased levels of water vapor in the atmosphere.
