Area Forecast Discussion National Weather Service Miami FL 911 AM EST Fri Jan 22 2021

UPDATE. Early morning fog/mist across the region has finally lifted, giving way to plenty of sunshine. Strong high pressure will keep it dry and quiet yet again today across South FL with temperatures climbing close to 80 degrees by this afternoon. MFL's 22/12Z sounding measured a PW of 0.68 inches, which is below the 25th percentile for this date, along with a pretty strong sfc inversion and low-level subsidence inversion at around 940 mb. In fact, you can tell there is an inversion off our radar (KAMX) with all the ground clutter returns. There was so much clutter that the radar kept switching into "convective" mode as opposed to "clear air" mode. Aside from fun facts and sunshine this AM, no significant change to ongoing forecast is anticipated, with dry conditions prevailing.

PREV DISCUSSION. (Issued 631 AM EST Fri Jan 22 2021)

AVIATION(12Z TAFS) . Patchy fog across South FL early this AM will primarily affect the SE terminals, including KFXE, KMIA, KTMB, and KOPF. FG/BR/low CIGs are expected to lift around 14-15z, giving way to VFR conditions and SW winds in the 8-10 kt range. Mainly VFR overnight though some patchy fog, perhaps locally dense, is expected mainly from 9-14z Saturday AM for moreso the Miami-Dade airports (KMIA, KTMB, and KOPF) along with the KAPF along the Gulf Coast. However, possible IFR to even LIFR conditions are possible if dense fog materializes. At this time kept forecast on the lower side of MVFR, though as we get closer in time may have to introduce IFR CIGs/VIS. NW to N winds Saturday.

PREV DISCUSSION . (Issued 334 AM EST Fri Jan 22 2021)

SHORT TERM (Today through Saturday) .

A stationary boundary currently draped across the southeast CONUS will begin to ooze southward on Saturday, briefly dethroning the high pressure that has been anchored across the region the past few days. Ahead of the future approaching boundary, the high's axis has already shifted southeastward across the area and will continue eastward into the Atlantic, keeping flow out of the SW to WSW through the period. Aloft, mid-level ridging will hold firmly in place, helping to reinforce warming temperatures into the weekend, along with keeping PoPs virtually nonexistent.

Only meteorological phenomenon to monitor will be the potential for patchy fog each morning across low-lying and fog-prone areas as the orientation of the low-level flow maintains sufficient enough boundary layer moisture. A few localized areas may become dense before sunrise.

LONG TERM (Saturday Night through Thursday) .

Medium range model guidance depicts a mean upper-trough over the western CONUS and broad anticyclonic flow developing over the eastern two-thirds of the CONUS until around mid/late-week, when the upper-trough is forecast to evolve eastward across the eastern CONUS.

Saturday Night into Sunday:

A mid/upper-level speed maximum will eject off the mid-Atlantic coast, as surface high pressure translates eastward in it's wake. This large-scale evolution will allow a backdoor cold front to move through the area from the western Atlantic waters from Saturday night into Sunday, with associated increasing rain chances across the eastern half of South Florida during this time. That being said, rain chances remain generally low owing to the weak/shallow frontal circulation and lingering dry/stable air aloft associated with a mid/upper-level ridge. There is some uncertainty regarding the coverage of showers for Sunday, as Atlantic coastal convergence could locally augment low-level ascent and lead to slightly higher coverage of shallow rain showers over the east coast metros.

Monday and Tuesday:

The previously mentioned mid/upper-level ridge will be centered over the western Atlantic waters -- supporting southerly low-level flow and west-southwesterly flow aloft. This vertical wind profile is indicative of warm air advection, which combined with rich boundary- layer moisture may support coastal showers across the Atlantic waters off South Florida. Again, lingering dry/stable conditions aloft should keep rain chances and coverage rather low. The enhanced positive theta-e advection and persistent ridge aloft will support a period of above average temperatures (warmest on Tuesday), with high temperatures climbing into the lower to middle 80s across South Florida.

Remainder of the Week:

The mid/upper-level ridge will shift westward and become centered directly over South Florida, leading to light surface winds and stable conditions aloft. This will support a continuation of above average temperatures, with lower 80s forecast across South Florida each afternoon. In addition, we will be monitoring fog potential through this period -- supported by light/variable surface flow and persistent rich boundary layer moisture. By Wednesday, the previously mentioned upper-trough over the western CONUS will progress eastward -- supporting the initial development of a weak frontal wave which should track eastward across the southern CONUS through late-week. Present indications are that more substantial surface cyclogenesis will occur off the Carolinas Coast on Thursday in response to strong upper-level forcing. This will lead to the development of a trailing cold front (potentially robust) across the eastern Gulf of Mexico -- which should move toward South Florida late in the week. Model guidance is fairly consistent with a strong cold front moving through the area, though differences in timing of the frontal passage remain evident.

AVIATION(06Z TAFS) .

Generally VFR conditions expected through the taf cycle, with lower vis from patchy FG/BR possible through 12z. Will continue to monitor through the overnight and handle with amendments. Otherwise, light and variable SW flow gradually increasing this afternoon while also becoming WSW by the end of the period.

MARINE .

High pressure across the local waters will maintain benign marine conditions over the next several days with no meaningful weather impacts anticipated. By late weekend, a weak frontal boundary will move across the waters with cautionary conditions possible early next week in it's wake with building swell and seas across the northern Atlantic waters.

BEACHES .

An elevated rip current risk may exist early next week for the east coast beaches as northeasterly swell builds into the Atlantic waters of South Florida.
