Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Vfr and MVFR conditions across the area overnight andVFR should
be predominate during the day on Thursday. Patchy fog is expected
north this morning with a front remaining stationary across the
south. Rain is not anticipated until very late in the period or
after this TAF period.

primarilyVFR conditions expected through the period, although
some patchy MVFR vsby or ceilings may develop overnight near
terminals that received heavier rainfall totals. Light winds will
be seen on Thursday, mainly out of the s-sw and less coverage of
showers and thunderstorms is expected as well.

Prev discussion... (issued 248 pm cdt Wed jul 18 2018)
short term... Tonight through Friday
showers and thunderstorms continue to move through portions of the
state... Mainly in the far northern and southeastern regions of the
natural state. A nearly stationary boundary across the north has
allowed convection to train across the impacted area. As the storms
linger over already saturated areas, anticipate that some flash
flooding is possible, if not likely. Additionally, pwat values
measured in the 12z sounding were around 2.02 inches which is
nearly 0.50 inches above average for today. Despite large amounts
of instability this afternoon (3,000-4,000 j kg mucape), due to
the aforementioned showers and thunderstorms, as well as mostly
cloudy skies for a large portion of the day, have retained a
mostly capped environment.

The ridge of high pressure sitting over the southwestern CONUS will
continue to amplify and allow a shortwave trough to form around the
periphery, across the northern great plains. The low pressure system
will keep northerly flow over the area, and allow for some low end
rain chances across the far northern and eastern portions of the
state. With less rain expected Thursday and Friday as the ridge of
high pressure to our west builds, have much warmer temperatures are
expected. In addition to high temperatures in the mid to upper 90s
across the north, and over 100 degrees across central and southern
portions of the state, expect humidity to stick around, causing heat
index values to be 105 degrees or greater across central and
southern arkansas. Therefore, a heat advisory has been issued for
Thursday and Friday afternoons.

Long term... Friday night through Wednesday
a decent shot at a frontal passage will exist in the long term.

Timing through arkansas looks to be Saturday. Given its probability,
there should be some relief in temperatures heading into the weekend
as surface winds shift to the nw. Moisture will be limited so pops
will be on the low side. The remainder of the weekend and into early
next week, we will be sandwiched between a ridge over tx and a
trough over the ohio river valley. There will be opportunities to
see bouts of convection as we return to NW flow.

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.
