A similar weather pattern for today as recent days with a moist air mass in place, chance of PM showers and thunderstorms and a high temperature near the 90 degree mark. Any thunderstorm that forms over the next couple of days can feature some heavy rainfall given the high available moisture content in the atmosphere. The next few days will feature high pressure over the north Atlantic which will stretch southwest to the Florida Peninsula and it’ll keep our general wind flow from the south. As a result, the very warm and humid conditions will continue right into the weekend.

The overall weather pattern around here in coming days will feature an abundance of low and mid-level moisture and this will result in a pretty good chance each day for scattered PM showers and thunderstorms. The western Atlantic Ocean ridge of high pressure has strengthened and will pump into the region the very warm and humid air in the lower levels of the atmosphere. Elsewhere, the Atlantic Basin tropical scene looks rather quiet and should stay so for the next several days. One final note, the annual Perseid meteor shower will peak next week…best to look for meteors in the pre-dawn hours of Tuesday, Wednesday and Thursday.

The overall weather pattern around here in coming days will feature an abundance of low and mid-level moisture and this will result in a pretty good chance each day for scattered showers and thunderstorms. The western Atlantic Ocean ridge of high pressure has strengthened in the wake of “Isaias” keeping Florida and a warm and humid regime. As far as the tropics are concerned, it looks like a lull in the action for the Atlantic Basin during the next several days.

The western Atlantic Ocean ridge of high pressure will rebuild over the next couple of days and keep Florida in a very warm and humid region with scattered afternoon and evening showers and thunderstorms. As far as the tropics are concerned, it looks quieter on that scene as well with a lull in the action for the Atlantic Basin which has had a very active season so far.

After producing lots of rain and wind in the Carolinas on Monday night, “Isaias” will continue to pick up forward speed today and push along a stalled out frontal boundary zone to a position over the Delmarva Peninsula/southern New Jersey by late in the day. Torrential rainfall will spread northeastward along the I-95 corridor today and continue into this evening with as much as several inches possible by the time Wednesday morning rolls around. In this area and in the wake of the tropical system, temperatures climbed to 90+ degrees on Monday and they’ll likely reach 90 degrees for highs during the remainder of the week. In addition to the heat, it’ll remain quite humid around here with a daily shot at showers and thunderstorms.

“Isaias” will push to the north today to a position just off the coastline of Georgia and then likely make landfall tonight somewhere in the Carolinas – perhaps as a hurricane. After that, “Isaias” will move along the rest of the eastern seaboard bringing torrential rain in its path resulting in a significant rain event from Florida to Maine when all is said and done. There is plenty of low-level moisture left behind in the central part of Florida and that will contribute to the daily shot at showers and thunderstorms over the next couple of days with temperatures likely reaching the lower 90’s for afternoon highs.

“Isaias” weakened slightly yesterday into “tropical storm” status and it remains so early Sunday morning despite a burst of deep convection in the overnight hours. That burst of thunderstorm activity has not resulted in any significant improvement in the overall structure of “Isaias” which is currently about 40 miles southeast of West Palm Beach, FL and it is not outside the realm of possibility that it regains enough strength later today to reach weak hurricane status. Nonetheless, “Isaias” will ride up to fairly close to the east-central coastline of Florida with some heavy rainfall and strong winds to last about 12 hours or so once they begin later this morning. On Monday, “Isaias” will begin to take a turn to the north and then northeast and likely make landfall somewhere in the Carolinas - perhaps as a hurricane. After that, “Isaias” will continue to ride up along the east coast and generate a major rain and wind event for the Mid-Atlantic and Northeast US - ultimately resulting in impact extending all the from Florida to Maine.

“Isaias” became the second hurricane of the 2020 Atlantic Basin tropical season in the overnight hours as it pulled away from the island of Hispaniola and out over the very warm waters of the southwest Atlantic Ocean. The 2020 Atlantic Basin tropical season has gotten off to a very active start - now with nine named systems – and it will very likely remain quite dynamic as we begin the month of August. In fact, a couple other tropical waves are now churning over the eastern and central tropical Atlantic - virtually guaranteeing the energetic season will continue in coming days. Hurricane “Isaias” is likely to continue on a NW track over the next 24-36 hours that will bring to a position just off the east coast of Florida this weekend with significant impacts to the Bahama Islands and southern/eastern Florida. “Isaias” is now classified as a category 1 hurricane and there is a chance it intensifies to a category 2 storm before it makes its closest approach to Florida’s east coast. After that, “Isaias” may very well ride up along the east coast ultimately resulting in a significant rain event all the way from Florida to eastern New England.

“Isaias” has intensified into a category 1 hurricane in the overnight hours and continues to head on a northwesterly track that will move it over the Bahama Islands during the next 12-24 hours and then likely to a position just off the east coast of Florida by Sunday. As a result, heavy rain and strong winds will likely arrive in the southern and eastern parts of Florida by later tomorrow night and continue through the day on Sunday. There remains the possibility that the core of the hurricane could impact the barrier islands and immediate coastal areas, with hurricane force gusts and damaging wind potential later in the weekend. By Monday, "Isaias" is likely to push towards the Carolina coastline - perhaps as a hurricane - and then it could take a ride up along the Mid-Atlantic and Northeast US coastlines early next week. Stay tuned for updates later today and continue with preparations along the east coast of Florida for significant rain and strong winds.

The 2020 Atlantic Basin tropical season has gotten off to a very active start now with nine named storms - the newest one being “Isaias”. Tropical Storm “Isaias” has been pounding away at Puerto Rico since last night with torrential rainfall and is now interacting with the island of Hispaniola (Haiti/Dominican Republic). This particular island has mountainous terrain with peaks of over 10,000 feet and it is likely to limit the intensification of “Isaias” – at least in the short-term. In addition, an interaction with this northern Caribbean island frequently causes a “re-positioning” of the low-level circulation center of a given tropical cyclone so we’ll look for that to take place over the next 12-24 hours. After that, Tropical Storm “Isasis” is likely to significantly impact the Bahama Islands - perhaps as a hurricane - and likely take a track over or just off the east coast of Florida with substantial rainfall and strong winds on the table. There is a chance that the moisture field of the tropical storm then rides up along the southeast US coastline to the Carolinas - and potentially as far north as the Mid-Atlantic/Northeast US.
