Area Forecast Discussion National Weather Service San Juan PR 335 PM AST Fri Aug 7 2020

SYNOPSIS. A mostly benign weather pattern is expected throughout the weekend and into early next week as mid to upper- level ridge and a relatively dry air mass prevail over the area. The next tropical wave is expected by the middle of next week.

SHORT TERM. Tonight through Sunday .

Shower and isolated thunderstorm activity across the area should diminish by the early evening hours as a much drier air mass behind a quick moving tropical wave arrives. Therefore, mainly fair weather conditions with a slight chance of a few showers can be expected overnight. The weather pattern during the upcoming weekend is expected to be fairly benign as the combination of a mid to upper-level ridge and a drier than normal air mass will serve to limit shower activity across the area. Low-level moisture may still be sufficient enough to generate some overnight and early morning passing trade wind showers across the local waters, briefly affecting portions of eastern PR and the USVI, followed by the development of afternoon convection across western Puerto Rico. Significant rainfall accumulations are not expected. Somewhat hazy skies due to the presence of suspended Saharan Dust particulates are also expected. However, significant dust concentrations are not expected.

LONG TERM. Monday through Saturday .

PREV DISCUSSION. /issued 429 AM AST Fri Aug 7 2020/

To start the workweek, high pressure will dominate all levels of the atmosphere in the central Atlantic, with a secondary high extending into the western Atlantic. This will promote fairly benign conditions across the region, with the usual easterly winds at 10 to 20 mph. Patches of low-level moisture are expected to pass through Monday and Tuesday, yet very dry and warm air aloft will make conditions hostile for shower activity. The moisture moving through will likely drive some showers over western Puerto Rico for both Monday and Tuesday, but these showers will likely be unimpactful. Though the showers will not be very strong, persistent showers over a given area can still produce ponding of water.

The next tropical wave arrives Wednesday in the afternoon or evening. Generally the models have been trending to a somewhat weaker system, yet this wave will still very likely increase shower and thunderstorm activity across the region. Forecast models suggest the wave will last through Thursday morning, after which more dry air will move in. During the wave, the biggest threat will be urban and small stream flooding. Only passing showers are expected once the wave moves out and through Friday. Models suggest another tropical wave arrives for Saturday evening.

AVIATION. Approaching tropical wave will cause VCSH across the local terminals in PR and the USVI this afternoon. However, VCTS is possible at TJBQ/TJMZ through 08/21Z. The winds will be from the east to ESE at around 15 kt with occasional gusts this afternoon, decreasing to 10kt or less after 08/00Z. ISOL/SCT SHRA overnight but the terminals are expected to remain VFR.

MARINE. Fairly tranquil seas of between 2 and 5 feet are expected to continue through early this evening. However, fresh easterly winds of up to 20 knots later tonight and throughout the weekend will result in choppy seas of up to 6 feet, mainly across the offshore Caribbean waters and Mona Passage. A return to more tranquil seas is expected by early next week as the winds diminish.
