Area Forecast Discussion National Weather Service San Juan PR 430 AM AST Fri Jan 22 2021

SYNOPSIS. Mainly fair weather conditions with patches of low- level moisture enhancing cloudiness and isolated to scattered shower activity from time-to-time will be the dominant weather pattern during the next few days. Remnants of a cold front will drift across the area by midweek, but significant rainfall accumulations are not anticipated. Winds will remain light to moderate from the east to northeast, while choppy marine conditions along with a moderate to high risk of rip currents will continue through Saturday.

SHORT TERM. Today through Sunday .

At mid to upper levels, a polar trough is moving east and away from the local islands, while a ridge starts to gradually move in over the local islands. Below normal moisture will move in over the local area today and persist through the weekend, causing only a slight chance of rain for the local area. However, scattered showers in the afternoon is forecast across the interior sections and western Puerto Rico this afternoon.

Drier than normal air is present over Puerto Rico. This is causing mainly fair weather over Puerto Rico and the USVI, but isolated light showers are occurring over the local waters. That said, slightly higher moisture is being observed over the local waters, and is expected to continue over the waters through the day, which may cause a continuation of isolated waters over the waters. Also, slightly higher moisture is expected this afternoon across the western half of Puerto Rico, and thus scattered showers are forecast across central to western PR this afternoon. According to the hi-res guidance, some areas may observe enough rain to cause ponding of water on roadways and poor drainage areas. The daytime temps are expected to be near normal, with the lower elevations being in the low to mid 80s while the higher elevations will be in the mid 70s to low 80s. For Saturday and Sunday, even drier air is expected for the weekend, and little to no shower activity is expected across the local islands. Fair weather will prevail this weekend. The wind will remain moderate but the easterly winds will become more northeasterly on Sunday. Daytime and nighttime temps will be near normal.

LONG TERM. Monday through Friday .

Model guidance continues to suggest that mainly fair and stable weather conditions will dominate the local weather conditions through most of the long-term forecast period, with patches of low-level moisture generating brief periods of cloudiness and isolated to scattered shower activity from time-to- time. The frequency of patches of low-level moisture may increase by midweek as the remnants of an old frontal boundary drift into the forecast area. However, model guidance does not suggest significant moisture content, with model- estimated precipitable water vapor briefly peaking around 1.30 inches by Thursday afternoon. Mid-level ridging will promote subsidence and drier air aloft, conditions that will also limit any chance for organized convective development. That said, significant wetting rains are not anticipated through at least Friday afternoon, which will continue to support further deterioration of soils and fuels moisture, while promoting favorable fire weather conditions.

Thereafter, model guidance suggests that the remnants of yet another frontal boundary will drift into the forecast area by Friday night. Under somewhat favorable conditions aloft and enhanced moisture content, there may be a higher chance for significant wetting rains. However, it is too soon and there is low confidence in the impacts, if any, this feature could bring to our area.

AVIATION. Mainly VFR conditions expected across the local terminals. Brief -SHRA will continue near the vicinity of the USVI terminals this morning. VCSH possible at TJPS and TJSJ after 22/16Z as SCT SHRA develop over portions of PR. Light and VRB winds will be observed until around 22/12Z, but East winds and sea breeze variations at around 10 KT are expected thereafter until around 22/22Z. FEW to SCT SKY expected today.

MARINE. Light to moderate winds at 5-15 knots are expected across the local waters during the next few days. Fairly tranquil marine conditions will prevail across most of the local waters through the end of the week. However, a small northerly swell will invade the Atlantic waters today into early Saturday, creating choppy seas across the outer Atlantic waters where small craft operators are urged to exercise caution. There is a moderate risk of rip currents for beaches along the north coast of Puerto Rico, eastern coast of Vieques, all coasts of Culebra, and western coast of Saint Thomas. The risk will elevate to high for beaches along the north coast of Puerto Rico this evening.

FIRE WEATHER. KBDI continues to approach fire danger thresholds, with a potential to surpass 550 for Camp Santiago today. Although significant wetting rains are not anticipated and relative humidity may drop into the mid to upper 40s across the southern coastal plains of Puerto Rico, winds are forecast to remain below 15 mph. Overall, the expected weather pattern appears marginal for fire weather conditions, but the threat should remain low today. Nevertheless, lack of wetting rains will continue to support further deterioration of soils and fuel moisture, with a chance to favor an elevated to critical fire danger threat within the next few days.
