Aviation
Vfr conditions expected through the TAF period. A weak cold front
will move through the region after 10z, but only a shift in winds
from SW to NW will occur. Winds will return to the south towards
the end of the period across the terminals before going light and
variable during the late evening hours. 20

update...

minor changes to forecast package this evening. Clear skies and
light winds has allowed temperatures to fall quicker than
originally anticipated. In some areas, temperatures have already
dropped to near the previous forecasted low. Decided to bump low
temps down several degrees as a result. Also, added some clouds
to the grids as scattered high clouds will move over the region
from the northwest during the overnight period. Otherwise, expect
dry conditions with mostly clear to partly cloudy skies. Overnight
lows will range from the upper 30s in our northern and eastern
zones to the low to mid 40s across the remainder of the region.

short term... Tonight through Tuesday night
most locations should see mostly clear skies from subsidence from
the surface ridge overhead tonight. A persistence forecast to
continue into Tuesday. More dry weather is anticipated even
though another upper trough moving across the middle mississippi
river valley will bring another relatively diffuse frontal
boundary into the area. This front is not expected to have much
impact on our weather with the exception of affecting wind
direction. In fact, the front will likely dissipate by late
Tuesday afternoon. With more sunshine and dry westerly winds,
daytime temperatures should warm into the lower 70s areawide.

Overnight lows will warm into the upper 40s lower 50s Tuesday
night into Wednesday morning as southerly winds return to the
region.

Long term... Wednesday through Monday night
Wednesday will be a transition day across the four state region as
upper level ridging will dominate much of the plains and into the
lower miss valley to start the day with this ridge axis aloft
quickly sliding east of our region Wednesday night. The first in a
series of shortwaves will eject out of the southern great basin
during the day Wednesday and eject into the plains, remaining well
north and west of our region. Low level moisture return will be
ongoing during this time as well and we cannot rule out some late
day showers across our extreme northwest zones Wed aftn in response.

Southwesterly flow aloft increases in the Wed night Thu time frame
as a closed area of low pressure aloft continues to spin across the
four corners region of the country. Embedded disturbances within
this flow aloft and increasing low level lift via isentropic
processes will result in increasing rain chances, mainly across our
northwest half late Wed night and through much of the day on
Thursday. It appears a longwave trough entering the northern plains
on Thu will push south and east into the ohio valley and it's this
westerlies trough that will help to pick up the closed energy across
the southwest conus. Thus, upper forcing becomes more widespread
across more of our region Thu night and through the day Friday.

There will be a cold front associated with the upper trough with the
front expected to get its best push into our region during the day
Friday from northwest to southeast. The front should exit our region
Friday night with a drier and somewhat cooler weekend ahead but not
cold by any means. Confidence is increasing with the late thu
through Friday evening timing of the greatest rainfall chances given
that the slower ECMWF has sped up with its 12z run today and has
caught up to the more progressive GFS canadian progs which now are
all in agreement with a dry weekend.

The drying trend does not hang around long as another longwave
trough quickly dives into the intermountain west early next week
with rainfall likely back in the forecast sometime late Monday night
or into Tuesday.

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.
