Updated for the 06z aviation discussion below.

Vfr conditions will prevail through the period, with only some mid
and high clouds noted at times. A few isolated showers could occur
through 08z in the vicinity of klit, but otherwise no weather
impacts are expected during the next 24 hours.

Observations from kadf are still missing so will continue with
amd not sked there.

update...

hrrr has backed off on the small rain chances over the SE on the
latest run or two but a few very weak returns are showing up on
radar at this time. Temp dew point spreads are in excess of 10
degrees where the echoes are showing up so most likely nothing
more than sprinkles are hitting the ground.

With weak short wave still expected to move through and into an
area that is a little more moist, will keep the silent precip
chances going. Remainder of the forecast also looks good with only
a tweak or two needed.

short term... Tonight through Monday
the cdfnt that brought the active wx to ar on Fri fri night, was
located well S of ar this aftn. Nly sfc winds behind the fnt contd
to usher much drier air into the region, as noted by sfc dewpoints
ranging fm the mid 50s to mid 60s. At the same time just 24 hours
ago, we were looking at dewpoints in the mid 70s to arnd 80 degrees.

Meanwhile, a good bit of mainly high lvl clouds have kept mid aftn
readings generally in the 70s.

Hi-res model data does show some potential for small rain chcs late
tngt ovr the SE half of the fa, as a weak upr short WV passes acrs
the area. With much drier airmass in place in the low lvls, plan to
not mention any pops tngt attm, but wl let evening shift monitor
later model data.

Otherwise, still looking at a mostly dry fcst thru the pd sfc high
pres prevails. We will see a nwly flow aloft cont as well thanks to
a broad upr trof ovr the ERN half of the nations, with an upr rdg
persisting ovr the rockies. Small chcs for convection wl return to
the fcst ovr NRN ar later on mon, as a weak upr impulse drops sewd
towards the state. Temps wl cont below seasonal norms the next few
days, which is not often mentioned for ar in late june.

Long term... Monday night through Saturday
the extended period will start with high pressure at the surface and
aloft over the region. This will bring dry conditions, mostly sunny
skies with highs a bit below normal. On Wednesday, the surface high
pressure is forecast to move east of ar, as a return south flow
comes back to ar. Some weak upper energy is possible in northwestern
ar areas, and with an approaching surface system in the plains, a
slight chance of convection may develop. But at this time kept the
chance of rain low due to uncertainty. On Thursday, a bit better
chance of convection may be possible, as better upper short wave
energy and improved south flow sets up into ar. The heating in the
afternoon and early evening will be the best chances, but again only
a 20 to 40 percent chance is forecast. Friday and into the weekend,
models do show the best upper lift and a possible frontal system to
sag closer to possibly into ar, and this would bring the best chance
of convection.

As mentioned, temperatures will start mild for this time of year,
with lows in the 60s and highs in the 80s. A gradually warming trend
and increase in humidity will be seen as the week continues.

Lzk watches warnings advisories None.

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.
