May gets underway on Friday, and it looks like a cooler-than-normal pattern will dominate in the eastern half of the nation to at least the middle of the new month. Multiple cooler than normal air masses are likely to push into the north-central states from central Canada during those next couple of weeks and these will ultimately spread to the south and east and encompass the Great Lakes, Mid-Atlantic, and Northeast US. A favorable pattern for the transport of cooler-than-normal air masses from Canada into the US will feature a persistent upper-level trough centered near the Great Lakes as well as some “high-latitude blocking” up across northeastern Canada and Greenland. In addition to the expected cooler conditions, multiple rain events are on the table during the next couple of weeks beginning with one from later today into early Thursday which will impact the Mid-Atlantic region.

An unsettled weather pattern will bring us the chance for more showers and thunderstorms today with the jet stream more activated than normal for this time of year and displaced farther to the south. This “activated” jet stream is the atmosphere’s response to the initial signs of El Nino conditions in the tropical Pacific with warmer-than-normal water temperatures now observed at surface level.

Low pressure will head towards the northeastern states here at mid-week and it should bring us a decent rainfall from later today into early Thursday and a strong-to-severe thunderstorm can be in the mix. High pressure takes over for the late week and then we’ll have to monitor a coastal storm on Saturday. This system can sideswipe us with some rainfall to begin the weekend or it could just miss us to the south and east....in either case, the weekend will be on the cool side and the cool pattern will continue well into May.

An unsettled weather pattern will bring strong-to-severe thunderstorms to northern Alabama today and some of the rain will be heavy at times with as much as a couple of inches in localized areas. The overall unsettled pattern will continue into May as the jet stream has become activated and displaced farther south than usual for this time of year. This unsettled pattern will result in additional severe weather threats as well in coming days across the Tennessee Valley.

A weak frontal system will approach the region later today and it can bring us a shower or two, but nothing is expected on the significant side. A stronger low pressure system will head towards the northeastern states later Wednesday and it will likely bring us some much welcomed decent rainfall from later tomorrow into early Thursday and there can be a thunderstorm mixed into the picture. High pressure takes over for the late week and we’ll have to watch a coastal storm for Saturday as it could skirt the region with some shower activity or just miss us to the south and east.
