What's New / NOTES
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis..A light to moderate south to southwest wind flow continues through Monday as high pressure slowly shifts east. A weak frontal boundary stalls near the coast Monday night into Tuesday morning leading to decreased winds and seas through midweek. An increased coverage of showers and Thunderstorms can also be expected through midweek. A generally light southerly flow develops late in the week into the weekend.

425 am cdt Sun may 28 2017

Near term now through Sunday night
Surface and upper ridge remain in place and slowly move east this
afternoon and tonight as the next upper trough approaches. This will
keep conditions mostly dry as deep layer subsidence continues.

However, rain chances will begin to increase this afternoon and
especially tonight from the west as the upper ridge slides east and
the trough nears. Temperatures continue to run 3 to 5 degrees above
normal, with highs in the upper 80s and low 90s away from the coast.

Highs near the coast will be in the low to mid 80s. Lows tonight
will also be above normal, in the low 70s inland to mid 70s along
the coast. 13

Short term Monday through Tuesday night
The memorial day forecast has resulted in lots of deliberation,
discussion, and consternation by this forecaster. In short, the
finer details will likely be dependent upon the convective evolution
over the next 18 to 24 hours. And, as such, will be subject to
change. Here's how things appear to evolve for the time being,
though.

Broad upper-level troughiness is expected to stretch from the upper
midwest and across the ohio valley for much of Monday. The nature of
this synoptic setup will likely result in rather weak perturbations
traversing the region until the main trough heads east. With weak
(if any) cross isobaric flow, the associated cold front will be
sluggish to move into our area and probably do so during the
afternoon. However, if convection develops along the front earlier
than expected, don't expect much southward movement.

To pour salt into the uncertainty wound, synoptic scale kinematics
and thermodynamics are out of phase with this system. The main upper
jet axis remains stretched from southwestern missouri into southern
pennsylvania through the day, with any upper-level divergence
remaining closer to the jet. Surface to 6-km effective bulk shear
values remain focused along the front and *may* reach 35 knots along
and north of the us-84 corridor by late afternoon if the front sags
south eastward into our area.

Abundant boundary layer moisture will be present, with precipitable
water values close to 3 standard deviations possible just inland
from the coast. There will be sufficient instability present, with
forecast soundings indicating MLCAPE values between 2000 and 2400
j kg possible. This combined with the possibility of an approaching
front (and any mesoscale boundary interactions), will lead to the
possibility of strong thunderstorms Monday afternoon. Areas along
and north of the us-84 corridor will likely see the greatest threat
for 50 mph wind gusts from the stronger thunderstorms. Right now,
though, it appears the greatest severe weather threat will be
north east of our area.

Another piece of upper-level energy is expected to move into the
upper trough Tuesday afternoon, which may aid in pushing the front a
little farther south. With abundant low-level moisture, especially
in vicinity of the weakening front, shower and thunderstorm
probabilities will remain elevated through the rest of the short
term period.

Thanks to WFO birmingham for collaboration this morning. 02

Long term Wednesday through Saturday
A weakening surface boundary is expected drift offshore Wednesday as
a shortwave rounds the base of the upper trough over the eastern
u.S. Even with its probable location just offshore, the boundary
will likely continue serving as a focus for shower and thunderstorm
development across the region. With the loss of stronger synoptic
scale forcing, the convective nature should become increasingly
diurnal in nature, with the greatest coverage expected during the
afternoon and early evening. With uncertainties in the location and
timing of the front, this diurnal nature was not reflected
precipitation probability forecasts for Wednesday.

Forecast confidence lowers thereafter given temporal and spatial
discrepancies between the deterministic output of the major medium
range models. Based on signals noted in the naefs, I still have
confidence that ridging will attempt to reassert itself over the
southeast toward the end of the week heading into next weekend. With
some indication being noted that the diffuse boundary *may* try and
waffle back onshore, shower and thunderstorm probabilities will
remain above climatological values. However, I suspect the presence
of ridging should allow the diurnal trend to largely be maintained.

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.
