a small area of showers and storms over southwest kansas
and far northwest oklahoma has developed behind an outflow
boundary this morning. The outflow will reach wwr by
19z with a risk of a shower storm. MVFR conditions are possible
with a storm or two over northwest oklahoma, otherwiseVFR
conditions will prevail with a southerly wind. Additional storms
will develop late this afternoon evening and will mainly impact
northern and western oklahoma.

convection continues to develop along a southward moving
outflow boundary in southern kansas this morning. Expect
this will gradually weaken, but a wind shift will move into
at least parts of northwest oklahoma by early afternoon.

During the afternoon and evening, additional showers and storms
will develop north and west of the area with a gradually movement
into parts of northern oklahoma. Will also need to watch if
additional storms can develop near along the previously mention
outflow boundary. Inverted v environment will certainly support
the risk of damaging winds with storms late this afternoon evening.

vfr conditions to continue. Some mid and high clouds will
gradually increase late today and into this evening, especially
across north. There is a chance for a few storms at wwr late this
afternoon into this evening and at pnc late in the forecast. Some
precip may get as far south as i-40 late tonight, but chances
remain too low to mention outside northern sites. Winds will
remain southerly at 8 to 12kts.

dangerous heat indicies continue today...

another hot and humid day is expected today. The oun RAOB had a
850 mb temperature of 24 c last evening. 850 mb temperatures are
progged to be ~23 to 24 c at oun and ~22 to 27 c across the area
today. Therefore, high temperatures are forecast to be in the
upper 90s and low 100s f (once again) today.

Dewpoints yesterday afternoon were in the low to mid 70s f across
north central into east central oklahoma (e.G., 73 f at the
blackwell mesonet and 74 f at the chandler mesonet at 4 pm). Based
on these observations, opted to increase dewpoints above guidance
at these locations for today. Therefore, the heat advisory was
expanded northward to the kansas oklahoma border as dewpoints will
likely remain high enough for 105+ f heat indicies.

As a mid-level trough digs across the midwest, the attendant cold
front will move into western kansas later today. Showers storms
with the front may move into northwest and northern oklahoma late
afternoon into the evening; however, convection is expected to
generally weaken as it approaches oklahoma. Gusty winds will be
the primary hazard with any thunderstorms with relatively high
temperature-dewpoint spreads and downdraft cape. Elevated
convection will remain possible across the northern half of
oklahoma during the overnight hours due to isentropic ascent
associated with a low-level jet.

By Thursday into early Friday, a shortwave trough is forecast to
approach from the northwest. The coverage of showers and
thunderstorms is forecast to be greatest during this period with
convection spreading southeastward during the overnight hours. The
highest probabilities appear to be across northern into eastern
oklahoma. Precipitable water values are forecast to be ~1.8-2.0",
so heavy rainfall is possible.

For Friday afternoon, there is quite a bit of uncertainty as
convection will be modulated by the location of the remnant
surface boundary from the previous night's convection. Low
confidence continues on Saturday with a moist airmass and remnant
boundaries still expected in the area. Temperatures should be
relatively cooler both days with the cloud cover and convection.

A warming and drying trend will begin on Sunday as mid-level
heights rise.

By Monday and Tuesday, the mid-level ridge is forecast to expand
and move eastward into the southern plains. Opted to raise
temperatures based on the synoptic pattern and deterministic
surface temperature data. Temperatures are forecast to become hot
once again with highs in the upper 90s and low 100s f. There are
indications a cold front may approach the area toward the end of
the forecast period as a longwave trough digs across the northern
plains.

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.
