Area Forecast Discussion . UPDATED National Weather Service Mobile AL 529 PM CST Mon Dec 9 2019

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. 00Z issuance . General VFR conditions were noted across the area at 23Z with an area of low end MVFR CIGS along and west of Mobile Bay. General low end MVFR conditions are expected to become IFR with local LIFR conditions along and just north of the I-10 corridor as southerly winds over the area weakens to around 5 knots or less. Impact to operations at area TAF sites are possible after 06Z as dense fog forms. Conditions are expected to improve after sunrise to low end MVFR CIGS and VFR VISBYS. A slowing cold front moves south across the area Tuesday, bringing scattered rain showers along with drops in conditions to the IFR/MVFR juncture. The I-20 corridor is expected to be impacted after 21Z Tuesday afternoon. South winds 5 to 10 knots will become northerly around 10 knots as the cold front moves south across the area. /16

PREV DISCUSSION. /issued 410 PM CST Mon Dec 9 2019/

NEAR TERM /Now Through Tuesday/ . A CONUS-wide trough is currently present aloft, with a prominent shortwave over the southwest CONUS. This feature is expected to progress eastward over the southern CONUS tomorrow and towards the southeastern CONUS through midweek. A surface cold front will also approach the region late tonight into early tomorrow, increasing showers from the northwest. Model reflectivity shows showers in the form of a line, with scattered showers ahead of the line, that will move from northwest to southeast over the region through midweek. Model soundings for areas near the coast and even further inland show CAPE values generally between 200 and 700 J/kg Tuesday morning and through the afternoon. Therefore, this combined with frontal forcing will lead to the possibility of a few thunderstorms as the line moves through Tuesday morning and through the afternoon.

The other concern will be the potential for fog development tonight into early tomorrow morning due to southerly flow leading to increased warm and moist air. Some of this fog may become dense towards dawn, particularly for Mobile Bay, Mississippi Sound, and areas surrounding. Model guidance from the SREF and HRRR also supports this. Thus, a Dense Fog Advisory was issued from tonight through mid-morning tomorrow for Mobile Bay and Mississippi Sound areas. Will monitor through the evening to see if the advisory needs to be extended to the land areas as well.

Temperatures will continue to run above seasonal norms tonight, with lows around 60 degrees further inland (SW AL and SE MS) and in the mid 60s along and south of I-65. Highs tomorrow will be in the upper 70s for areas south of I-65, but highs will be lower in the interior SW AL and SE MS due to FROPA. Expecting highs to only reach the mid to upper 60s in this region. /26

SHORT TERM /Tuesday night Through Thursday night/ . A cold front associated with an upper trough over the lower Mississippi River Valley pushes offshore Tuesday night, ushering in a cooler and more stable low-level airmass. Aloft, the upper trough lags to the west, with an unsettled southwest flow continuing and showers lingering across the area throughout the day Wednesday. Rain chances end over inland areas Wednesday night as the upper trough departs to the east, though a slight chance continues right along the coast. Another trough moves east across Texas right on the heels of this one, with southwest flow returning aloft by Thursday night as it approaches the lower Mississippi River Valley. Rain chances increase across the entire area Thursday and Thursday night in response to the impinging trough. /49

LONG TERM /Friday Through Monday/ . The upper trough over the lower Mississippi River Valley continues east across the Deep South during the day Friday. A surface low develops over the northern Gulf as the upper trough takes on a slight negative tilt. The low moves quickly northeast, but in doing so keeps the local area in its northwestern quadrant and firmly entrenched in a cool and stable airmass with daytime temps hovering in the 50s across much of the area. Above the stable surface layer, however, south to southwest flow prevails and enough mid-level instability develops for a chance at some elevated convection mixed in with the showers. Best rain chances Friday and Saturday will be over the eastern half of the area, in closer proximity to the passing surface low and beneath the best region of upper divergence associated with the passing trough. Drier air finally moves into the area Sunday and Monday, with skies clearing and temps climbing back into the 60s. /49

MARINE . Light to moderate onshore flow will persist through tomorrow afternoon. Areas of marine fog may restrict visibility tonight over bays and sounds and adjacent near shore waters. Thus, Dense Fog Advisories may be needed tonight. Winds will then shift from onshore to offshore and increase dramatically across the marine area Tuesday night as a cold front moves east over the region. Thus, a Small Craft Advisory was issued and is in effect from Tuesday night through Friday morning. Moderate to strong easterly flow will then take hold for late week, especially over the open Gulf waters. Light to moderate northwest flow will then follow for the beginning of the weekend. /26

MOB WATCHES/WARNINGS/ADVISORIES. AL . High Rip Current Risk through late Tuesday night for ALZ265-266.

FL . High Rip Current Risk through late Tuesday night for FLZ202-204- 206.

MS . None. GM . Small Craft Advisory from 9 PM Tuesday to 6 AM CST Friday for GMZ631-632-650-655-670-675.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
