515 pm cdt Thu apr 25 2019

Short term Low pressure will move out of the area through the
tonight. High pressure will build in and bring mild and dry
conditions to the entire CWA through early next week. Low
humidity, clear skies and seasonal temperatures will be the result
over the weekend. A light return flow will begin on Sunday as high
pressure builds to the east of the area.

Long term
Strong upper level ridging over the atlantic southeast usa will
be the dominant feature Monday and Tuesday. A strong cutoff low
over southern california will eject northeastward as a short wave
out ahead of it moves eastward over the northern and central
plains on Wednesday into Thursday. Models show a weakening in the
ridge and an occluding low over the northern plains bringing
slight chances of rain back into the area by mid to late week.

Therefore... Front stalls to our north. Lots of uncertainty on how
far south the front will stall..Leaving the possibility that the
area... Especially the southern cwa... Could remain mostly dry on
Thursday.

Aviation
Expect conditions to improve this evening as a line of storms moves
through the forecast area. Expect MVFR toVFR conditions to prevail
tonight after the storms move through. Thunderstorm should end by 0z
for the entire area. Winds will shift to the northwest tonight.

ExpectVFR conditions to prevail on Friday.

Marine
Low pressure exits area overnight. Increased pressure gradient
between these two features will cause winds to be high end small
craft exercise caution through tonight. High pressure will then
build in and bring light winds and calm waters through the
weekend. Light return flow begins Sunday and continues through
early next week as high pressure slides to the east.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
