Ifr MVFR CIGS will likely develop overnight across parts of
northwest ar, with conditions improving after 14-15z.

Thunderstorms should develop along an approaching cold front
and possible impact kbvo before 00z. The better chances of
storms will hold off until after 00z however.

excessive heat Monday followed by the threat of strong to severe
thunderstorms Monday evening are the main forecast concerns
today.

Afternoon dew point values Monday are expected to rise to
oppressive levels... In the upper 70s to lower 80s... Across much of
northeast oklahoma and the arkansas river valley, with only
slightly lower dew points across the rest of the forecast area.

With temperatures warming into the low to mid 90s across much of
the area, the result will be afternoon heat index values ranging
from 105 to 113, except a bit lower in far northwest arkansas.

Thus have issued an excessive heat warning for parts of northeast
oklahoma and also the arkansas river valley, with a heat advisory
for the rest of eastern oklahoma.

As a cold front enters the area late Monday afternoon or early
evening, strong to severe thunderstorms are expected to develop
near the front given very strong instability, with large hail and
damaging winds being the main severe weather hazards. The severe
threat will likely diminish after midnight as the storms move into
the southern part of the forecast area and weaken some.

Shower and thunderstorm chances may persist Tuesday and Wednesday
across southern parts of the forecast area, with cooler and drier
air to the north providing some welcome relief from the very humid
conditions we have seen recently.

Another frontal boundary will move into the area by Friday night
and Saturday bringing additional chances of showers and
thunderstorms, and keeping temperatures a few degrees below the
seasonal normals.

Made a few adjustments to the national blend of models pops early
this week, with only minor changes after that time.

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.
