SHORT TERM. (Today and tonight) Issued at 226 AM CDT Fri Aug 14 2020

Rather strong elevated instability and elevated warm-air advection is over the northern and eastern parts of our forecast area early this morning. Satellite indicates some mid-level clouds that suggest ACCAS formation, currently from near Oklahoma City to Ada, drifting southeast. So far, radar echoes have been absent in this area, but storms have already formed farther east, mainly near the Arkansas border, with with a few isolated echoes near Okmulgee and Talihina. Based on all this, we have a mention of isolated storms or a slight chance of thunderstorms over our eastern counties for early this morning.

Very moist air in northern Oklahoma, being forced upward by easterly winds over rising terrain, may produce patches of fog this morning, mainly over far northwest Oklahoma.

Later today, temperatures over the southern and central parts of our area will have high temperatures from the upper 90s F to near 110 F. Generally, the higher the maximum temperature, the lower the dew point temperature. In any case, it appears that the highest heat indices will be in the existing Heat Advisory area.

Scattered storms are expected to form this evening over the Panhandles. It is not out of the question that a few might drift into Oklahoma, though the probability is currently very low.

CmS

LONG TERM. (Saturday through Thursday) Issued at 201 AM CDT Fri Aug 14 2020

A heat advisory will be in effect Saturday afternoon for much of Chickasaw and western Choctaw Nations. This is expected to be the last very hot and extremely humid day of the recent heat & humidity wave. Beginning Sunday the strong upper high center that has been over western TX and NM the last several days will reposition to the west over AZ and UT into late next week. This will allow the southern plains to be under the influence of northwesterly flow from the central high plains on the eastern flank of the high. One upper wave is expected to pass around the eastern edge of the high over KS and OK early Sunday and possibly again early Monday. These mornings will see the best chances of showers/thunderstorms mostly west of I-35. Beyond Monday, weak waves around the eastern part of the high may provide overnight showers or thunderstorms through Thursday. Temperatures will decrease and provide a noticeable break to the very hot and humid conditions of the last week.

AVIATION. (06Z TAFS) Issued at 1023 PM CDT Thu Aug 13 2020

Main challenge continues to be with wind direction as surface low tracks southeast across western into central/southern overnight into the day Friday. Winds speeds will however remain below 12kts. Otherwise, VFR conditions expected at most sites. Exceptions will be WWR/PNC where a period of IFR ceilings will occur. More certainty remains at WWR.

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.
