The Tennessee Valley will remain on the western periphery of an upper-level ridge of high pressure both today and on Saturday and this will keep us quite warm with highs well up in the 80’s. In fact, the warmest day in the next few is liable to Sunday when temperatures peak in the upper 80’s ahead of an incoming upper-level trough. Meanwhile, low pressure will develop over the Bahamas this weekend and will slowly intensify as it makes a move to the northeast over the relatively warm waters of the southwestern Atlantic. This system may end up being classified as the first official “tropical” system of the 2020 Atlantic Basin tropical season.

The east coast of the US will be an interesting area to monitor over the next week or so in terms of the weather as we’ll see a tropical system just east of Florida in the near term and then perhaps a coastal low by the end of next week which could impact the Mid-Atlantic. Low pressure is now forming over the Florida Straits and it’ll intensify over the next 24-48 hours as it makes a move to the northeast over the relatively warm waters of the southwestern Atlantic Ocean. This system may come uncomfortably close to the US east coast in coming days and may play a role in the development of a coastal low by the end of next week in the Mid-Atlantic region.

The weather today will feature a dramatic warm-up as high pressure now over the western Atlantic will promote a stronger southerly flow of air into this region from the Gulf of Mexico. Temperatures this afternoon will likely peak in the low-to-mid 80’s and they’ll stay in that general zone right through the upcoming weekend. The flow of air from the Gulf of Mexico will also become increasingly moist and this will lead to an increasing chance of showers and thunderstorms by the late stages of the weekend. Elsewhere, low pressure will form near or over the Bahamas during the next 24-48 hours and it could become the first "official" tropical system of the 2020 Atlantic Basin tropical season as it intensifies and makes a move to the northeast over the SW Atlantic.

The weather around here will feature a dramatic warm-up over the next few days with quite a jump in temperatures this afternoon as high pressure shifts off the east coast. From this location, the high pressure system will pump in much warmer air into northern Alabama riding in on increasingly strong south-to-southwest winds. Temperatures beginning on Thursday afternoon will reach into the 80’s and this return of summer-like weather will continue right through the upcoming weekend.

The weather around here will feature a dramatic warm-up later this week as high pressure shifts off the eastern seaboard. From this location, the high pressure system will pump in much warmer air riding on increasingly strong southwesterly winds. Temperatures will reach the 80's beginning on Thursday and this return of summer-like weather will continue right through the upcoming weekend.

Another cold shot is coming to the Mid-Atlantic/Northeast US for the first half of the week and it could lead to more record or near record low temperatures and the possibility of frost during the next couple of late nights. As with the remarkable cold air outbreak this past weekend, attention should be paid to sensitive vegetation with this unusual late season chill. The end of the week will bring about a dramatic turnaround and summer-like warmth is quite likely on Friday as a “Bermuda-high” type pattern develops over the eastern US and Atlantic Ocean.

One more chilly air mass is pouring into the northeastern quadrant of the nation, but as high pressure pushes off the east coast at mid-week, the temperature pattern will change dramatically in the eastern half of the nation. High temperatures around here will be held in the mid 60’s today as we start the new week, but climb to summer-like levels late in the week in the low-to-mid 80’s. It looks like the summer-like weather will continue right through the upcoming weekend as well.

A cold front will approach the region today and result in an increasing chance of showers and thunderstorms. It’ll turn colder in the overnight hours following the passage of the cold front and it stays on the cool side to start the weekend. On Sunday, Mother’s Day, there will be a cold start to the day, but sunshine will boost afternoon temperatures to near 70 degrees.

A large dome of high pressure will push into the region today and maintain a relatively cool and dry pattern across the northern part of Alabama. Another cold front will approach the area late tonight and on Friday giving us an increase in clouds and a chance of showers, maybe a thunderstorm. It’ll turn even cooler by the early part of the weekend with temperatures below normal on Saturday as northwest flow develops following the passage of a strong cold frontal system. Mother’s Day (Sunday) may get off to a very cool start, but sunshine should boost temperatures to near 70 degrees during the afternoon hours.

Today is an unusually chilly day in the Mid-Atlantic region with temperatures far below-normal for the 6th of May aided by a low-level easterly flow of air and thick cloud cover. In fact, high temperatures today in much of the Mid-Atlantic region will be confined to levels rarely experienced for this time of year. Believe it or not, this air mass may pale in comparison to what is on the way for the early part of the weekend.
Quite an amazing outbreak of cold air will arrive in the Mid-Atlantic region and Northeast US on Friday night and the cold frontal passage may actually be accompanied by a rain-changing-to-snow event – even into higher elevation suburban locations just to the north and west of I-95. Saturday will turn out to be a very windy and unusually cold day in much of the northeastern quadrant of the nation with temperatures in the DC-to-Philly-to-NYC perhaps more than twenty degrees below normal. While Sunday, Mother’s Day, will remain colder-than-normal, the afternoon will become much more bearable when compared to Saturday as there should be far less in the way of wind and plenty of sunshine. Looking ahead, cold air outbreaks will likely continue into mid-May across the central and eastern US, but a pattern change to warmer looks like it’ll begin during the 3rd week of the month - and tropical season may not be far behind.
