Area Forecast Discussion . UPDATED National Weather Service Mobile AL 1008 PM CST Sat Dec 7 2019

DISCUSSION. See updated information for land areas below.

UPDATE. The overnight forecast was mostly in good shape and only minor adjustments were made to increase cloud coverage slightly and to account for hourly temperature/dewpoint trends. Skies should remain mostly cloudy overnight as a deck of stratocumulus extends over much of the area. A light northeasterly to easterly flow should prevail on the northern fringe of an inverted trough of low pressure extending across the north central Gulf. Weak isentropic ascent may result in the development of a few light rain showers over our Gulf marine zones overnight, and it is possible that isolated showers could reach as far north as coastal areas overnight into early Sunday morning. We left a slight chance of rain in place near the immediate coast. Overnight lows are on track to range from around 50 degrees over southeast MS and adjacent southwest AL, with readings in the lower to mid 50s over most of the rest of south central AL and the northwest FL panhandle. /21

PREV DISCUSSION. /issued 535 PM CST Sat Dec 7 2019/

DISCUSSION . Updated for latest aviation discussion below.

AVIATION . 00Z issuance . Scattered to Broken MVFR level clouds are expected through the night under northwest to north to northeast flow around 5 knots as a surface trough over the northeastern Gulf meanders west. Upper end MVFR CIGs expected Sunday with east, then southeast winds around 10 knots returning to the area as the Gulf trough moves southwest of the forecast area. A few light showers are possible over areas southeast of I-65, but are not expected to impact operations. /16

PREV DISCUSSION . /issued 357 PM CST Sat Dec 7 2019/

NEAR TERM /Now through Sunday/ . The mid-level shortwave that brought rain yesterday has now pushed well east of our area today. This left a weak surface low/trough over the northern Gulf as high pressure begins to build over the eastern US. The remnant surface low/trough will begin to retrograde back west tonight in response to the surface high. This will keep an unsettled pattern over the area through the day Sunday. Scattered showers will begin over the Gulf tonight ahead of the trough and slowly build southeast of I-65 during the afternoon.

Temperatures tonight will likely be moderated by a mid-level cloud deck in advance of the trough. Expect lows to range from near 50 in our northwestern areas to mid 50s at the coast. Clouds and showers will likely limit high temperatures tomorrow to the upper 60s to maybe low 70s at the coast. BB/03

SHORT TERM /Sunday night through Tuesday night/ . Isolated to scattered showers remain possible over far eastern portions of the local forecast area Sunday night into Monday morning as a weak surface trough rotates through from the south and winds become more onshore. As these showers depart to the northeast during the day Monday, rain chances begin to increase once again from our west as a cold front approaches. The front itself pushes through late Tuesday, bringing more widespread rain chances and even some potential for a few rumbles of thunder right along the front itself. High temps range from low to mid 70s Monday and mid 60s behind the front to mid 70s ahead of the front on Tuesday. Overnight lows start off mild, with mid to upper 50s Sunday night and upper 50s to low 60s Monday night. A cool down is expected behind the front Tuesday night as temps dip into the mid to upper 30s over northwestern counties and low to mid 40s elsewhere. /49

LONG TERM /Wednesday through Saturday/ . A weak surface low develops along the frontal boundary over the north central Gulf and moves northeast Wednesday into Wednesday night. With the low passing to our south, expecting north winds and stable low-level airmass to remain firmly entrenched, leading to a stratiform cool rain across the area. Rain ends over inland areas Wednesday night and temperatures dip into the low to mid 30s. Meanwhile, closer to the coast and offshore, a few light showers may continue through the overnight hours and cloud cover helps temperatures remain in the upper 30s to low 40s. Another deep upper-level trough digs across the Plains states Thursday into Friday. Ahead of this trough, unsettled southwest flow continues to support shower activity across the area Thursday night through Saturday. Highs remain in the 50s through the long term and lows gradually trend slightly warmer back into the 40s. /49

MARINE . Light to occasionally moderate onshore flow will slowly become easterly tonight as a weak surface trough/low retrogrades west across our marine zones. On the east side of the low, the gradient will tighten and a moderate southeasterly flow will likely develop over the eastern offshore waters. Winds tonight will be borderline small craft advisory criteria in a very localized area but not confident enough to issue a Small Craft Advisory; nonetheless, small craft should exercise caution. By Sunday, onshore flow will develop in advance of our next cold front. Sunday night into Monday morning could see some patchy fog over the nearshore waters and Bays of Alabama and Florida. Behind the front, moderate to strong offshore flow will develop and a Small Craft Advisory will likely be needed Tuesday night through Wednesday night. BB/03

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