Area Forecast Discussion National Weather Service San Juan PR 824 PM AST Mon Jan 20 2020

UPDATE.

GOES-16 detected cloudiness and moisture associated with a dissipating old frontal boundary. Winds will continue from the southeast across the region. Under this wind flow, the current moist air mass will be replaced by a drier air mass later tonight into tomorrow, limiting shower activity across the islands and increasing afternoon maximum temperatures during the afternoon hours. However, the typical wind-driven rains and diurnal induced afternoon showers will continue to affect the local islands each day.

AVIATION.

Clouds and -SHRA/SHRA will continue across the local flying area. Some of these SHRA/-SHRA will affect JSJ/IST/JPS/NCM/KPK overnight from time to time. SHRA activity will diminish aft 21/20z. The wind will blow from the ESE-SE at 10 kt or less increasing at 10-15 kt after 21/13z.

MARINE.

Mariners can expect hazardous seas through at least Tuesday evening. Therefore, small craft advisories are in effect for the local waters. The combination of a northerly swell and wind- driven seas will maintain seas up to 10 feet overnight. Breaking wave heights between 10 and 13 feet can be expected with this swell action. Refer to local marine products for additional information.

PREV DISCUSSION. /issued 219 PM AST Mon Jan 20 2020/

SYNOPSIS . The cold front that pushed into the area Saturday night and Sunday, bringing pervasive showers, is slowly backing away and drier air is invading from the southeast. A stronger cold front will move into the area from the northwest late Thursday and Friday with more shower activity. Although drying is expected behind the front over the weekend moisture will return by mid week next week.

SHORT TERM . Tonight through Wednesday . The cold front that pushed into the area Saturday night and Sunday, bringing pervasive showers, is slowly backing away and drier air is invading from the southeast. Only light showers are currently indicated over Puerto Rico or the U.S. Virgin Islands at 12:30 PM AST. Low level flow, as indicated by shower motions is clearly east southeast, but there has been sufficient warming over Puerto Rico to produce slightly onshore winds on the north coast of Puerto Ricoand temperatures under a partially hidden sun have been slow to rise but are still in the low to mid 80s in the lower elevations. Only scattered showers are expected tonight and Tuesday in the drier air and these shwoers will focus mostly on the windward southeast-facing plains and slopes of Puerto Rico, except that currently the GFS is forecasting an area of moisture to develop just east of the area and move east until it gets over the U.S. Virgin Islands. Then that moisture is to move northwest with little effect in Puerto Rico. Therefore, POPs in the USVI are 40 and 50 percent, but generally less in Puerto Rico. With southeast flow continuing, the air over Puerto Rico will be slow to gain moisture as the front approaching from the northwest will not yeild any moisture until a pre-frontal band moves into the area Wednesday afternoon. At upper levels a passing ridge will flatten out over the area and flow will become westerly. A powerful jet will continue to develop northwest of the area and migrate over the local outer Atlantic waters with speeds of 90-100 knots. With drier air in place at mid-levels and generally increasing mid-level temperatures thunderstorms or heavy showers are unlikely.

LONG TERM . Thursday through Sunday . /issued 531 AM AST Mon Jan 20 2020/

By Thursday, the surface ridge across the Atlantic is forecast to shift farther northeast into the central Atlantic, as a cold front will move into the western and southwest Atlantic and approach the region. An associated amplifying mid to upper- level polar trough will also cross the west Atlantic and weaken the ridge now in place overhead. This will result in a weakening of the trade wind inversion and promote instability aloft through at least early Friday. The shift in the surface to the mid- level high pressure ridge pattern should also result in better low level moisture pooling and convergence as the frontal boundary is expected to arrive and sink southwards across the region by the latter part of the work week. Model guidance also continued to suggest a vigorous mid to upper level jet max crossing the region Thursday through Friday. The combination of the instability aloft and good low level moisture convergence accompanying the frontal boundary will therefore favor the development of scattered to numerous to showers with periods of locally heavy rains across the islands and coastal waters at least through early Friday.

By late Friday and into the weekend, model guidance still suggest lingering low level moisture but gradually improving and stable conditions aloft. Therefore expect less frequent early morning shower activity across the islands and coastal waters. This will be followed by isolated to scattered showers of short duration during the afternoon hours. Improving conditions are forecast by Saturday and through Monday, as the surface high pressure will once again build and spread across the west Atlantic, resulting in a more northeasterly wind flow and a stable near normal weather pattern.

AVIATION . VFR are conds are expected drg prd. SHRA/VCSH will continue through 20/23Z for TJBQ and TJMZ. VCSH are possible across TJPS AND TJSJ terminals dgr prd with conditions improving by 20/20Z. ESE winds of 10 to 15 kts with higher gusts.

MARINE . Seas will continue to diminish. Seas at the outer buoy were around 12 feet at 20/16Z and had fallen below 10 feet at the inner buoy. Nevertheless it will take some time for seas to become quiet enough to take down small craft advisories. Also seas are sufficient to extend the high surf advisory another 12 hours. The Coastal flood advisory has been allowed to expire.
