A potpourri of topics today ranging from another day with a strong thunderstorm threat in the Mid-Atlantic region to an active Atlantic Basin tropical scene to an update on Comet NEOWISE which is making its closest approach to Earth later tonight. First, on the weather threat in the Mid-Atlantic region, yet another wave of energy aloft will combine with considerable amounts of moisture in the low and middle levels of the atmosphere to bring another shot at strong storms later today and tonight. Second, on the tropics, an impressive tropical wave over the central Gulf of Mexico is likely headed to the east coast of Texas by the early part of the weekend and it will result in heavy rainfall in that part of the southern US. A second tropical system, Tropical Storm Gonzalo, has run into a bit of dry air which has halted its intensification in recent hours as it continues to push towards the Caribbean Sea. A third tropical wave has just emerged off the west coast of Africa and it may become an important player to monitor next week. Finally, Comet NEOWISE makes its closest approach to the Earth later tonight and it won’t be back around these parts for about 6800 years.

The Atlantic Basin tropical scene has become quite active with an impressive system over the Gulf of Mexico and also a tropical storm (Gonzalo) over the central tropical Atlantic. The Gulf system has a chance to intensify into a named tropical storm over the next day or so as it heads towards the northwestern part of the Gulf. Heavy rain is likely by the weekend from this Gulf system across much of Texas and Louisiana and it could make landfall somewhere along the east coast of Texas. Meanwhile, Tropical Storm Gonzalo could very well climb to hurricane status as it pushes towards the Caribbean Sea reaching that body of water this weekend.

The Atlantic Basin tropical scene has become quite active with an impressive system over the eastern Gulf of Mexico and also a newly named tropical storm over the central tropical Atlantic. The Gulf system has a chance to intensify into a named tropical storm over the next couple of days as it heads towards the northwestern part of the Gulf and Tropical Storm Gonzalo could very well climb to hurricane status over the next couple of days in the central Atlantic.
Elsewhere, a wave of energy in the upper part of the atmosphere is combining with a stalled out frontal boundary zone and plenty of moisture to spark some strong thunderstorm activity at mid-day in the western part of the Mid-Atlantic region and across the Ohio Valley. Some of these thunderstorm cells will make it into the I-95 corridor at day’s end and likely reach strong-to-severe levels with the potential of damaging wind gusts of up to 60 mph, hail, frequent lightning and heavy rainfall.

High pressure over the region will weaken some today and this will allow for a bit more in the way of thunderstorm activity over the next couple of days. Overall conditions will remain on the hot and humid side and this summer-like pattern will continue right through the upcoming weekend. Elsewhere, there are multiple tropical waves to monitor in the Atlantic Basin and couple more moving over Africa likely leading to an active period as we progress through the latter part of the month.

An even stronger wave of energy aloft will likely generate thunderstorms later tomorrow for the Mid-Atlantic region and some of these can reach severe levels with heavy rainfall, hail and potential damaging wind gusts. Elsewhere, the Atlantic Basin tropical scene has become more active with two systems to monitor over the next few days and additional waves are drifting westward over Africa assuring an active last stretch of the month of July.

High pressure over the western Atlantic continues to pump hot and humid air into the Tennessee Valley. In fact, the high heat and humidity will hold on all week as weak frontal passages will not be able to provide much, if any, relief to the area. Elsewhere, there are multiple tropical waves to monitor in the Atlantic Basin; however, there are no serious threats for the US mainland during the next several days.

High pressure at all levels of the atmosphere in the eastern US and over the western Atlantic continues to dominate the scene around here and this is leading to our extended stretch of hot weather. Temperatures should climb to the middle 90’s once again this afternoon and likely will reach that high level over the next couple of days. Showers and thunderstorms will be scattered over the next couple of days across the Tennessee Valley, but will tend to increase at mid-week as a frontal system drops southeastward across the Northern Plains and towards the region. Elsewhere, a tropical wave of low pressure looks like it’ll travel from the northern Caribbean Islands towards the Gulf of Mexico over the next few days with a small chance of some intensification.

We are approaching the climatologically warmest time of the year for the Mid-Atlantic/Northeast US/Great Lakes regions of the country and it looks the weather pattern will live up to those long-term averages. The hottest weather of the season so far will begin this weekend and continue through the middle of next week. The hottest days during this stretch for the I-95 corridor will likely turn out to be Sunday and Monday when temperatures should climb to the mid and upper 90’s in the DC-to-Philly-to-NYC-Boston corridor.

High pressure continues to dominate the scene around here and is leading to an extended stretch of hot weather across the northern part of Alabama. One high pressure center has pushed off the New England coastline and another sits over the southeastern part of the nation. Both of these will consolidate this weekend over the western Atlantic Ocean into the familiar “Bermuda-high” type of pattern and this will produce a stretch of hot and humid conditions in much of the eastern US. Elsewhere, the Atlantic Basin tropical scene continues to be quiet partly as a result of some dry, desert air that has pushed to the west from northern Africa; however, there are signs that the “African-wave train” may get quite active later this month.
