Near term (rest of today)
issued at 749 am cdt Mon aug 19 2019
extensive mid and high clouds are found in advance of an elongated
5h trof axis. Have adjusted sky grids to account for this trend.
Virga and perhaps a few sprinkles were occurring in portions of north
central and northeast al. With few clouds behind the trof axis,
expect the hottest temps to be in NW al shoals area where the current
heat advisory resides. Isolated thunderstorms still look reasonable
later this afternoon per latest hrrr guidance.
Short term (tonight through Wednesday night)
issued at 345 am cdt Mon aug 19 2019
any ongoing convective activity should rapidly diminish after sunset
this evening. Scattered cirrus clouds are expected to continue
overnight, with mild low temperatures in the low to mid 70s.
Tomorrow, the upper level ridging builds farther northward into the
central plains. Although heights over the tn valley do not
significantly change, increasing surface convergence will lead to
higher thunderstorm coverage tomorrow than is expected today. Because
of this, high temperatures are limited to the mid 90s and heat
indices mostly remain between 100 and 105. However, some isolated
areas above 105 are possible, making additional heat advisories
possible tomorrow. Because of the axis of surface convergence
combined with possible remnant outflow boundaries, an isolated shower
or thunderstorm remains possible overnight tomorrow night as low
temperatures once again only decrease to the low to mid 70s.
As the upper level ridge remains over the central plains, the regime
of northwest flow aloft sets us up for higher chances for showers and
thunderstorms Wednesday into Wednesday night. Higher cloud cover and
rain chances will limit high temperatures in the mid 90s on
Wednesday. Pops were kept in the chance range for now, but as
confidence in timing and placement increases, I would not be
surprised if these were elevated to likely. Wednesday night will
continue to see elevated chances for showers and thunderstorms due
to a shortwave trough digging into the great lakes region. This
shortwave will push a surface low into the northeast, dragging a weak
surface boundary through the midwest and into the mid-mississippi
valley. Moisture convergence along this axis will see rain chances
pick up Wednesday night heading into Thursday.
Long term (Thursday through Sunday)
issued at 345 am cdt Mon aug 19 2019
after a very warm to hot first half of the week, slightly cooler
temperatures and wetter conditions are forecast across the tennessee
valley to close out the week. An upper low moving to the ese across
the hudson bay and quebec will help in the development of a surface|
low north of the great lakes on Wednesday, deepening as it moves
across the st lawrence seaway late in the week. A cold front trailing
behind this low, being pushed to the south by high pressure building
southward from central canada, will approach the forecast area. As
has been the case the past few days, the various medium range models
vary somewhat on where the boundary will actually settle.
Going with a blend, the front should reach the tn al border sometime
late Friday into Saturday. Before then, a persistent southerly flow
rounding high pressure off of the east coast will gradually increase
atmospheric moisture content, with precipitable water amounts rising
into the 1.8" to 2.1" range in the thu-sat timeframe. This moisture,
aided by lift from the approaching boundary, and a more unstable
atmosphere will yield good rain chances for the late week. The
gfs ECMWF canadian to a degree all painted showers over the region
during the late week with the frontal boundary, so went with likely
chances of showers and thunderstorms for Thu fri. More uncertainly on
where the front ends up and greater model spread yielded lower rain
chances for the weekend, but still in the scattered range (25-54%).
Gfs soundings suggest that stronger storms are possible on Thursday,
with gusty winds and locally heavy downpours.
More clouds and shower activity will put a damper on daily
temperatures. High temperatures on Thursday should range into the
lower 90s, and upper 80s for fri-sun. Low temperatures in the lower
70s thu-sat mornings, should cool to near 70 by Sunday morning.

issued at 604 am cdt Mon aug 19 2019
bkn ovc altostratus will continue to scatter and move eastward this
morning, leaving behind mostly clear skies. A scattered CU field will
develop late this morning with wind remaining 5-7 kts or lower.
Isolated showers and thunderstorms may develop later today, but the
highest confidence is east of the terminals, so no mention was made
in the taf. There is also a chance for patchy fog development
tomorrow morning, but confidence is too low to include at this time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
