Area forecast discussion, Dec 19, 9:31 AM CST, 4 hours 16 minutes before
Area Forecast Discussion National Weather Service San Juan PR 1131 AM AST Sat Dec 19 2020 .UPDATE... Showery weather prevailed across the north and east Puerto Rico through the morning hours. The northern Virgin Islands had a mixture of sunshine and passing showers. Under a northeasterly wind flow showers will move into the interior and southwest portion of Puerto Rico during the afternoon, and St Croix can expect a mixture of sunshine and quick passing showers. Conditions will improve after sunset when shower activity should diminish. The best chance to observe no rain during the afternoon is the northwest quadrant and the south central coastal portion of Puerto Rico. St Croix, St John and Vieques will have a slight chance of rain too. && .AVIATION... VFR conditions will persist with a passing showers at times mainly at JSJ/IST/NPM/KPK. SHRA will develop across the interior and SW- PR thru 19/23z. Winds will continue from the NE at 10-15 knots with higher gusts in sea breeze variations. Winds will become calm to light and variable aft 20/23z. && .MARINE... Expect marine conditions with seas at 5 feet or less and NE winds between 10-15 knots through at least Sunday, when a northeasterly swell is forecast to reach the local waters, deteriorating the Atlantic and Caribbean Passages conditions. && .PREV DISCUSSION... /issued 438 AM AST Sat Dec 19 2020/ SYNOPSIS...A mid-level high pressure will continue to dominate the local weather pattern and it is expected to persist through the weekend. Trade wind showers will affect the local area from time to time. A northerly swell will result in hazardous marine conditions from late Sunday into the workweek. In the mean time, a moderate rip current risk continues for the north and eastern coast of Puerto Rico and the U.S. Virgin islands. SHORT TERM... Trade wind showers across the regional waters moved from time to time over portions of northern and eastern Puerto Rico, as well as across the U.S. Virgin Islands. Up to a quarter of an inch was observed with this activity over the north-central municipalities of PR. Minimum temperatures ranged in general from the mid 60s across the higher elevations to the high 70s across coastal areas. A mid-level ridge extending over the local area from the western Caribbean, will promote an east to northeast trade wind cap over the region through the short term period. A cold front will remain far north over the Atlantic waters and a surface high pressure is expected to move quickly between Sunday and Monday over the western Atlantic. This will bring a more easterly wind flow by the end of the forecast period. While conditions are not favorable for thunderstorm development, enough moisture content at lower levels will be sufficient to induced diurnal shower activity over portions of the interior and west/southwest PR each afternoon. Across the USVI, the breezy trades will move quickly offshore any streamer type of shower activity that develops around midday each day. Scattered shower activity is expected during the overnight and early morning hours across the USVI and the northern/eastern sections of PR each day, as showers over the Atlantic and Caribbean waters are carried by the ENE trades. LONG TERM... Model guidance continues to show weather predominantly dominated by the mid level ridge spreading over our region from the western Caribbean during the long term forecast period. This will promote relatively stable conditions aloft. Additionally, a frontal boundary over western Atlantic will move eastward and stall north of our region by Thursday and quickly dissipate afterwards. This could momentarily bring favorable conditions aloft with 500 mb temperatures cooling to -8 degrees celsius. However, this will be short in duration but possibly increase areal coverage of shower activity with the presence of low level moisture for the latter part of the period. At the surface, a high pressure over western Atlantic will continue moving eastward over central Atlantic maintaining a gentle to moderate east northeast trade wind flow over the forecast area. Shallow areas of moisture embedded in this northeasterly wind flow will reach the islands from time to time. This will produce shower activity on a daily basis. Precipitable water values will vary from 0.75 inches on Tuesday morning sharply increasing up to 1.5 inches during the afternoon hours, with varying values between 1.0 to 1.4 inches onwards until the end of the workweek. Overall, isolated to scattered showers are expected to stream across the local waters into coastal areas of eastern and northern Puerto Rico and U.S. Virgin Islands during overnight and morning hours, while scattered shower development due to locally induced effects can be expected along the interior and western sections of Puerto Rico in the afternoon hours of each day. This weather pattern is expected to hold through the end of the workweek. AVIATION...Mainly VFR conditions are expected to prevail across all terminals during the next 24 hours. However, trade wind shra may cause brief MVFR cigs across TJSJ and the USVI terminals through the morning hours. SHRA is expected to develop btw 16z-22z over southwest PR, this may cause tempo MVFR cigs at TJPS. Low level winds ENE at 10-15 kts. MARINE...Seas at 5 feet or less are expected to prevail through today. A northerly swell is expected to arrive late Sunday into Monday, resulting in hazardous marine conditions, with seas reaching Small Craft Advisory criteria. A moderate rip current risk continues for the north and eastern coast of Puerto Rico, Vieques, Culebra and all beaches in the U.S. Virgin Islands. && .PRELIMINARY POINT TEMPS/POPS...
