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.

As with the last couple of nights, showers and thunderstorms
continue to linger after sunset and work on any remaining
instability from the day. Have tweaked pops according to current
conditions. The hi-res models do not currently have a great handle
on the situation. However, if persistence holds tonight, activity
should diminish in coverage and intensity after 10pm. Do think
isolated low end sct storms could linger well into the overnight
hours. 00z sounding shows pwats have increase to over 2" this
evening and the bl winds remain at or below 10kt. Heavy rainfall
will be the primary hazardous weather mode, but still can't rule
out a strong isolated severe thunderstorm... At least before

short term tonight through Tuesday night ...

seems to be no real focus for thunderstorm development again today
except for leftover boundaries. Heavy rain continues to be a
threat as storms are slow moving. Upper air shows a weakening
upper ridge with a broad trough forming over the southeast during
the period. Models indicating a front drifting into north ga
Tuesday afternoon evening with some drier air spreading into the
state. Still looks like basically a diurnal pattern through the
period... Although some storms could linger into the overnight
tonight. For Tuesday... Have kept pops in the 40 to 50 percent
range. For tomorrow night have dried out the far north after
06z... But left low pops for the remainder of the area. No big
changes to temperatures in the short term.

long term Wednesday through Monday ...

still appears area will see only slow shift to NW flow aloft this
week with broad upper ridge building over the western and central
conus and trough over the midwest states. By the weekend, however,
medium range guidance now showing high amplitude trough digging sse
into the eastern states on Saturday. While we may not see much
cooler temps, could see slightly drier air at sfc and aloft, though
chc of storms will continue with cold air aloft and stronger mid
level flow. Until then, will continue to see mostly diurnally-driven
afternoon and evening convection though with well above average pw,
could also see isolated overnight activity as well. As flow aloft
eventually becomes wnw, could see some development of MCS though not
seeing confirmation of this in model qpf.

Heat indices should remain 95 to 101, which is below advisory
threshold, through the extended though will continue to monitor.

Tropical activity thankfully still not seen in model progs or nhc

long term Tuesday night through Sunday ...

medium-range models continue to show an amplifying upper-level
pattern developing through the majority of the extended forecast
period. Frontal boundary settling into the southern portion of the
forecast area as we begin the period concentrates best pops across
the southern half of the area mid-week. Strong short wave and
associated surface front should increase pops areawide as we head
into the weekend. With moderate mid-level winds associated with this
system, combined with enhanced forcing and at least moderate
instability, we will need to keep an eye on the potential for an
increased severe thunderstorms threat. Noticeable divergence between
the GFS and the ECMWF for the latter portion of the period, but i
have kept at least chance pops through the end of this forecast


00z update...

scattered showers and thunderstorms are expected to linger for the
next few hours, but should diminish in coverage by 10pm. Do expect
ifr CIGS to develop again overnight. If persistence holds, a brief
period of vlifr is possible right around 12z. Synoptic winds
should remain on the west side.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
