A cool front will approach the region later today and it will add to overall instability around here for the next couple of days. As a result, there can be additional strong thunderstorms in the area as we head into the weekend and some of the rain that falls can be heavy at times. One tropical wave will continue to head westward along the Gulf coast today and there are other disturbances to track in the Atlantic Basin as this somewhat favorable pattern for tropical activity continues into next week.

Scattered thunderstorms are expected to develop once again this afternoon in the Tennessee Valley before diminishing late this evening and some of the storms can be on the strong side. Thunderstorm coverage will increase on Friday and Saturday as a cold front pushes southeastward into the region. A few strong to perhaps severe thunderstorms may accompany this frontal boundary and any rain that falls during thunderstorm activity can be heavy at times with gusty winds.

Abnormally strong upper-level ridging continues to dominate the scene in the northern US and the resultant hot, humid weather around here will continue through the weekend. The center of this high-level ridging will retrograde westward over the next few days and become centered over the interior western US by the end of the week. A frontal system will slide from the Great Lakes by the end of the week into the Mid-Atlantic region and it is likely to increase instability around here this coming weekend.

Abnormally strong upper-level ridging continues to dominate the scene in the Northeast US and Great Lakes as we begin the new work week and the resultant hot weather around here will continue through the week. The center of this high-level ridging will retrograde westward over the next few days and become centered over the interior western US by the end of the week.

Upper-level ridging will expand and intensify over the Mid-Atlantic region during the next few days and temperatures will respond here by climbing to the 90’s this afternoon and likely to repeat this on a daily basis well into next week. The heat will be accompanied by uncomfortably high humidity levels and there is little chance of relief from rainfall which will likely be quite scattered. This high heat and humidity will continue into at least the latter part of next week.

High pressure ridging will build into the Northeast US over the next few days and this will continue the pattern around here of very warm and humid conditions along with the threat of scattered showers and thunderstorms. In addition, the overall pattern of strong high pressure to the north this time of year opens the door for westward-moving tropical systems to head towards the Bahamas, Florida and the Gulf of Mexico. We’ll monitor this possibility for signs of tropical activity during the first week of July.

A surface high pressure system off the northeastern US coastline will get absorbed by a large-scale Bermuda High-type high pressure system. As a result, western Atlantic high pressure will remain in control around here during the second half of the week and for the upcoming weekend. Low-level moisture will be supportive enough for the formation of afternoon and evening scattered showers and thunderstorms and temperatures will consistently reach into the lower 90’s for highs over the next several days.

A strong surface high pressure system over the Northeast US will shift to a position off the east coast by later today and ultimately get absorbed by a large-scale Bermuda High-type system. As a result, a stretch of hot weather is all but certain for the Tennessee Valley from mid-week through the weekend and likely well into next week. Temperatures will climb into the 90’s for the next several days and there will be a daily shot at showers and thunderstorms.

A strong surface high pressure system over the southeastern part of Canada early this week will shift southeastward over the next few days to a position near Bermuda by week’s end. During the weekend, high pressure ridging aloft will build dramatically over the Northeast US and this type of pattern will very likely open the door for heat around here and tropical activity as we end June and begin the new month of July. As is typical with strong and persistent upper-level ridging over the Northeast US, the chances will increase for westward-moving tropical activity in the general region from the Bahamas-to-Florida-to the Gulf of Mexico. Stay tuned.

An upper-level trough will send multiple waves of energy our way over the next few days and the result will be numerous rounds of showers and thunderstorms. Thunderstorms can be on the strong-to-severe side in this upcoming stretch and the rain will fall heavily at times. The heat will be less intense today and for the next couple of days given the combination of clouds and occasional rainfall.
