. UPDATE .

AVIATION. CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Areas of dense fog have been observed over parts of NE OK including KBVO, KTUL, and KRVS TAF sites. Visibility will continue to be highly variable for the next few hours for these TAF sites. Once the sun rises, visibility should begin to stabilize with rapid improvement to MVFR conditions expected. Satellite is also tracking a band of clouds across northeast Oklahoma associated with a passing cold front. This cloud deck will likely bring MVFR ceilings to most TAF sites with the exception of KMLC and KFSM.

Another concern will be the gusty winds behind the aforementioned cold front. Winds are expected to gust between 25 to 30 knots at times for the east Oklahoma TAF sites. Northwest Arkansas will see gusty winds but gusts are only expected to 20 knots.

Finally, a period of rain will be possible for KMLC and KFSM later this afternoon and tonight. Rain intensity is expected to be light with minimal reduction to ceiling and visibility expected.

PREV DISCUSSION. /Issued 414 AM CST Mon Dec 9 2019/

DISCUSSION . Early this morning a surface low positioned along the Oklahoma Kansas border with light westerly winds and drier air was slowly pushing eastward into the region. Where these conditions were interacting with the low level moisture currently in place . areas of fog to dense fog were developing over far Northeast Oklahoma and Southeast Kansas. These conditions will remain possible into the mid morning hours across parts of Northeast Oklahoma before a cold front associated with a shortwave currently dropping southeast into the Central Plains moves into the region.

The cold front is expected to enter Northeast Oklahoma during the mid/late morning hours and spread east and southeast through the CWA today Behind the frontal boundary. gusty north to northwesterly winds in the 30 to 35+ mph range will be possible during the day and should weaken this evening and overnight as the shortwave exits the region. Temperatures look to also fall behind the boundary with highs in Northeast Oklahoma expected during the morning hours . while a more diurnal temp curve will be possible for Southeast Oklahoma into West Central Arkansas. Overall highs look to range from upper 40s in Osage county to mid 60s near the Red River.

A secondary shortwave within the southern stream is progged to move eastward across Texas tonight and Tuesday. In response . rain chances will become possible late this afternoon and continue overnight tonight before tapering off Tuesday morning across Southeast Oklahoma and West Central Arkansas. The main question to this forecast will be the timing of the exiting precip with the timing of the colder/drier air filtering into the region within the northerly low level flow. Latest indications would suggest that the majority of the precip should exit ahead of the colder air as the deep dry level airmass spreads southeast through the CWA With the expected light QPF. it would seem difficult for the precip to be heavy enough and last long enough to erode the dry layer to reach the surface Thus. have shifted pops south and east a bit overnight to account for this However. one factor to monitor will be wetbulbing effects . which could cool the surface quicker and increase the potential for wintry weather.

Even with the drier air spreading across the CWA . there still remains a small window late tonight and Tuesday morning of the colder air allowing for a light wintry mix of rain/freezing rain/sleet/snow to become possible. The greater potential would be over the higher terrain locations of far Southeast Oklahoma and West Central Arkansas before the precip ends At this time. little to no accumulations are anticipated which should keep impacts minimal.

During the day Tuesday . cool temperatures along with clearing conditions should spread over the region as the southern stream trof axis departs the region. Mostly clear skies Tuesday night will aid in low temps back in the 20s for most locations. Southerly winds return Wednesday ahead of a weak shortwave looking to cross the Plains Thursday/Friday. A lack of moisture should keep this wave dry for the CWA. Temperatures late week into next week look to get back into the 50s for highs. At the far end/just outside of the forecast package . another wave looks to move into the Plains at the start of next week which could bring about the next chances for precip. Will continue to monitor as latest data comes in.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
