Area Forecast Discussion
National Weather Service Mobile AL
324 PM CDT Tue Jun 23 2020

.NEAR TERM UPDATE /Now Through Wednesday/...An upper trof over
the eastern states broadens somewhat through Wednesday but
otherwise remains in place. An associated surface low is currently
located over the Great Lakes with a cold front which extends from
near the Ohio River valley to Arkansas. As the surface low moves
further off to the north, the trailing frontal boundary dips into
northern Alabama/Mississippi on Wednesday and stall. A surface
ridge remains in place over the northern Gulf and maintains a
southwesterly flow over the forecast area. This maintains a moist
pattern over the region through Wednesday with precipitable water
values near 2.0 inches. A modest series of shortwaves move across
the area within the base of the upper trof pattern today followed
by a stronger series of shortwaves on Wednesday. This trend and
the moist pattern will support likely pops for much of the area
this afternoon followed by mainly categorical pops on Wednesday.
MLCAPE values of 1500-2250 J/kg are expected today with values
ranging from 1000-1500 J/kg on Wednesday, moderated by increased
cloud cover and somewhat lower afternoon highs. Despite the moist
pattern, the 12Z sounding at JAN indicated abundant drier air
above 700 mb, also indicated in the LZK sounding above 600 mb.
It's difficult to determine how expansive this drier air region
is, but following with the RAP guidance the drier air likely
shifts into the forecast area today albeit with some modification
due to entrainment from convection. RAP DCAPE values of 1000-1500
J/kg hence look possible and expect the stronger storms to be
capable of strong to potentially marginally severe wind gusts this
afternoon. On Wednesday, there is the potential for another area
of dry mid level air to be advected from the northern Gulf into
the area, mainly the southern half, during the afternoon. This
would maintain the potential for strong to possibly marginally
severe downdrafts again on Wednesday, tempered somewhat by the
somewhat lower instability. Locally heavy rainfall will also be
possible with the stronger storms each day which could lead to
nuisance type flooding issues. Lows tonight range from around 70
well inland to the mid 70s at the coast. Highs on Wednesday will
be mostly in the mid to upper 80s. A moderate risk of rip currents
is expected through Wednesday. /29

&&

.SHORT TERM /Wednesday night Through Friday night/...Upper trough
over the eastern states moves little through Thursday before
finally pushing east off the Atlantic coast by Friday night. As a
result, we continue to see unsettled weather under its southern
periphery Thursday with scattered showers and thunderstorms
developing during daytime hours. At the surface, high pressure
continues to ridge from the western Atlantic into the southeastern
states, maintaining a southerly flow across the region. With
moderate instability and ample moisture available, could see some
gusty winds with stronger storms due to precip loading in
downdrafts. This would be in addition to the typical summertime
threats of frequent lightning and heavy downpours. Rain chances
drop off Thursday night as weak ridging builds over the area, with
only a slight chance for a few isolated storms over southeast
Mississippi on Friday. Low temps range from upper 60s to low 70s
inland and mid to upper 70s along the coast. Highs on Thursday
remain in the mid 80s where coverage of storms will be greatest,
and upper 80s to low 90s elsewhere. Temps on Friday will be warmer
due to the more sparse coverage in clouds and storms, with most
areas seeing low to mid 90s. Some locations could see heat indices
reaching the 100 to 103 degree range on Friday. /49

&&

.EXTENDED TERM /Saturday Through Tuesday/...Upper ridging weakens
as another shortwave trough ejects from the Desert Southwest over
the south Plains to our west. This, in combination with the
persistent southerly flow at the surface and in the lower
troposphere, will support diurnal summertime convection each day
through the weekend. Best chance for thunderstorms will be during
afternoon hours, with activity tapering off each evening with the
loss of daytime heating. Above-seasonal rain chances return
everywhere early next week as the upper trough rotates into the
lower Mississippi River Valley and upper forcing increases over
the local area. Temperatures change little throughout the period
(welcome to summer along the Gulf coast), with upper 80s to low
90s expected across much of the area each afternoon. Lows range
from low 70s inland to mid 70s along the coast each night. /49

&&

.MARINE...Will have Small Craft Exercise Caution wording this
evening for the near shore waters as well as Mississippi Sound and
southern Mobile Bay due to southwest winds near 15 knots. Locally
higher winds and waves are possible near scattered to numerous
showers and thunderstorms through the period. /29
