An unsettled weather pattern will continue today in the Tennessee Valley as a slow-moving upper-level low continues to have an impact on the region. This system will destabilize the atmosphere enough for scattered showers and thunderstorms on a daily basis into week’s end. By the end of the week, the overall pattern will evolve into a summer-like one and highs on Friday and both weekend days should be in the mid-to-upper 80's.

An unsettled week will today in the Tennessee Valley as a slow-moving upper-level low meanders over the area and it will hang around for another couple of days. This system will destabilize the atmosphere and increase the chances for showers and thunderstorms on a daily basis for the next few days and any storm that forms can be on the strong side. The overall pattern evolves into a summer-like one by the end of the week and highs on Friday and both days this weekend will be in the mid-to-upper 80's. Elsewhere, Tropical Storm Arthur will head on out-to-sea today after hitting the Outer Banks of North Carolina on Monday with gusty winds and heavy rain bands.

An unsettled week is headed to the Tennessee Valley as a slow-moving upper-level low will meander over the area for the next several days. This system will increase the chances for showers and thunderstorms on a daily basis as we progress through the week and some of the storms that form can be on the strong side. Elsewhere, Tropical Storm Arthur will impact the Outer Banks of North Carolina today and then curve to the east on Tuesday and out-to-sea. This is the first official tropical system of the 2020 Atlantic Basin season.

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.
