419 pm cdt Thu mar 30 2017

Discussion Showers and thunderstorms moved through the region
today with a few strong to severe storms and possibly a couple of
tornadoes. One of the more impactful features from today was how
heavy the rain was. Storms were very efficient and quickly dropped 1
to 2 inches of rain in a short time with some locations seeing 4 to
5 inches of rain. This could just be a little insight of things to
come late Sunday into Monday with our next major system.

The next 60 to 66 hrs will be dominated by ridging aloft but
Sunday/Mondays system will quickly begin to take shape. This
system is already moving onshore across the pacific coast. With a
very strong jet on the backside of the trough. With that you can
expect it to continue to dig west of the continental divide and
close off this evening before dropping into the 4 corners early
tomorrow. This potent closed low will be the antagonist for our
hazardous weather beginning sometime Sunday. Prior to this look
for dry weather and warm afternoon highs.

Sunday through Monday will be quite busy. The pattern is setting up
for a very heavy rain event and we will likely need to issue flash
flood watches for much if not all of the area. As the upper low
begins to lift across the southern plains we will quickly move under
increasing southwest flow aloft. Multiple favorable parameters will
be coming together to support about a 6 to 12 hour time frame of
heavy rain somewhere over the central gulf coast. Once again
divergence aloft will be optimal (possibly even better than today).

This will combine with a strengthening ll jet which will be pumping
in rich h85 theta E air of near 340k. H5 winds will also be
increasing with 50 to 65 kts moving through. Rich moisture will be
in place with pws possibly approaching 2.25". One more rather
concerning issue is that there will be instability to work with as
well. Showalters values will approach -5c and the k index could
actually be abv 40c. This indicates that we will see a good bit of
thunderstorm activity. The combination of all of these features
suggest very efficient storms. Wpc already had the area outlooked
with widespread 3 to 6 inches and as long as things set up over
the area this will be fairly easy to achieve and some areas could
easily see much higher values, probably topping double digits.

Locations and timing is still uncertain and the highest rainfall
totals will be very dependent on placement of features and could
easily be over western sections of the outlook area near btr or
could be all the way over to coastal ms. Hopefully over the next
few days we can get a better idea of where the heaviest rainfall
may occur.

If that was not enough given the amount of forcing, shear, and
instability we can not rule out embedded strong to severe storms.

Even tornadoes are possible especially given the amount of shear
expected.

Another issue we will encounter Sunday and until the front passes
late Monday will be tides. A deep fetch will set up and with the
strength of the winds anticipated over the coastal waters, water
will easily pile up along the coast. Combine that with an
increasing astronomical tide and the recipe is setting up for
coastal flooding issues along south facing shores.

Things should finally begin to quiet down weather wise Monday but we
may be dealing with river flooding issues. We should remain mostly
dry through the remainder of the forecast but a few showers could
impact the region Wednesday as the next front approaches. /cab/

Aviation Convection continuing to move eastward, and have
dropped mention of thunder from kbtr, kmcb, khdc, khum, and may
be able to drop new orleans terminals and kasd in the next hour or
so. Should be east of all terminals by 21z or so. Outside of
convection, MVFR toVFR conditions in place. Beyond 21z,
anticipateVFR conditions for the remainder of the forecast
period. Cannot rule out brief period of radiation fog around
sunrise, evening shift will need to monitor. /35/

Marine Gradient weakens overnight and winds should quickly
relax this evening. Return flow will quickly set back up late
tomorrow and increase through Saturday. As the next system begins
to take shape onshore winds will ramp up Sunday and we could be
dealing with high end advisory if not gale conditions. This
system will move through Sunday night and into Monday with another
round of strong to severe weather. The cold front will dive into
the region and should be through the coastal waters by late
Monday. Moderate to strong offshore flow will develop with this.

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.
