849pm CST Monday Nov 18 2019

Weak surface ridge will be across the region tonight with a dry northwest to north flow aloft. Therefore, should be a mainly quiet night weather wise. On-going forecast is on track and no changes needed at this time.

AVIATION... The possibility of some patchy fog overnight toward sunrise is the only issue with this forecast package. At this point will keep consistency going which has the possibility of MVFR (Marginal Visual Flight Rules) type visibility between 1910Z/1914Z. Otherwise, clear skies and light winds..

Short Term [Tonight through Wednesday]

There are no major changes in thinking with regards to the short term forecast compared to the previous forecast package. High pressure will remain over the region through Wednesday with temperatures gradually increasing each day. Aside from patchy ground fog in the mornings, no impactful weather is expected through Wednesday.

Long Term [Friday through Sunday]

An upper level trough is expected to move across the Lower Mississippi River Valley during the long term period. Model and ensemble guidance is beginning to narrow in on a consensus with regards to the timing and strength of the upper level trough. Most guidance is now in agreement that the associated surface cold front will move through the region during the day on Friday. The exact timing of the system will ultimately determine how much destabilization can occur ahead of the front. This will play a large role in the overall potential for thunderstorms and the possibility for severe weather with these thunderstorms. For now, included slight chances for thunderstorms on Friday along with the likely rain showers.

The latest guidance has trended toward a more progressive solution with the cold front and associated precipitation exiting the region overnight Friday into early Saturday morning. However, giving lingering uncertainty in the progression of the upper level trough axis, kept slight chance Probability of Precipitation in the forecast through the day on Saturday (even though these may be overdone). High pressure will build in behind the system, resulting in cooler temperatures and dry conditions for the second half of the weekend.
