. Aviation Update .

SHORT TERM. (Today and tonight) Issued at 344 AM CST Thu Feb 20 2020

The weather is much quieter today in the wake of our winter storm system. The snow has ended across our area, with the system now located to our south in central/southern KS. In it's wake skies have been clearing from north to south and temperatures have plummeted in the arctic airmass. Temps to start today are quite a bit colder than previously expected with KODX at -9F, and KLXN at -3F as of 09Z. Temps this frigid combined with fairly light winds in the 5-10 mph range are producing wind chills of -15 to -24F, which will linger into the first few hours after sunrise today before improving.

After our cold start this morning, temps will begin to moderate as the arctic airmass dislodges to the east. Our recent snow may impact temps by a few degrees and have kept readings fairly conservative and slightly cooler than guidance (in the 30-35 degree range). Snow amounts across the area will be reported this morning but the highest totals that we've heard of so far average around 1.5".

LONG TERM. (Friday through Wednesday) Issued at 344 AM CST Thu Feb 20 2020

The forecast Friday and Saturday remains dry with a warming trend, so our recent snow won't last long. Friday will see rising heights/warmer air advect across our region leading to above normal temps in the mid/upper 40s. While warmer, models have consistently indicated that winds will be steady/gusty from the southwest in a tight pressure gradient/deep mixing with wind gusts of 25-30 mph.

Saturday is still shaping up to be the nicest/warmest day of the upcoming weekend with some very nice temps well into the 50s with some model guidance suggesting the potential for readings to top out in the 60s. While winds won't be as quite as strong as Friday, model forecast soundings suggest the potential for increasing winds Saturday afternoon as mixing deepens with gusts of 20-25 mph.

The weather turns more active/wet on Sunday as a closed upper low pressure system moves out the south central Rockies and tracks across KS or near the KS/OK stateline. The latest operational GFS has a farther north track than the ECMWF however either way, a widepsread precip event is expected across KS into southern Nebraska. Precip type favors predominantly rain especially at the onset, but a mix or change to snow is possible as cold air is drawn into the system.

After this system departs, models diverge in the handling of an upper trough/closed low translating southeast from the Pacific Northwest across the northern and central Plains around the Tuesday time frame. The latest GFS weakens the system and has a farther east track than the ECMWF which favors a stronger/deeper trough across the plains with a colder airmass and the potential for accumulating snowfall. Uncertainty remains with this system next week due to the varying model solutions, so stay up to date on forecasts/model trends.

AVIATION. (For the 12Z KGRI/KEAR TAFS through 12Z Friday) Issued at 510 AM CST Thu Feb 20 2020

VFR conditions are forecast through the TAF period with clear skies and light/variable winds transitioning to the southwest behind a surface ridge axis.

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.
