. AVIATION UPDATE .
SHORT TERM. (This evening through Tuesday) Issued at 307 PM CST Mon Feb 17 2020
Recent water vapor imagery showing fairly quick zonal flow over the bulk of the CONUS with one minor wave working east across the upper Mississippi Valley and another entering the central Rockies. A cold front with the former wave was working its way southeast across central portions of Kansas at 20Z with modest southerly winds bringing dewpoints into the middle 40s and temps into the lower to middle 60s ahead of it. Scattered showers with even some lightning activity had developed in southwestern portions of Iowa. Visible satellite imagery indicates very little cumulus formation in northeast Kansas but went ahead with small precip chances in a few far northeast counties near the front this afternoon.
The cold front reaches the Red River area late tonight as the next upper wave approaches. Mid-level moisture will continue to stream overhead in advance of this wave and there are varying indications of modest isentropic upglide in the 305 to 295K layer across the southeastern quadrant of Kansas late tonight into early Tuesday morning. Confidence in enough ascent to bring precipition to the ground through the drying lower troposphere is not high, but have enough concern for a trace precip mention in southern areas. Temperatures falling into the middle 20s to lower 30s keep the bulk of this as a flurry mention. Skies should steadily clear through the day Tuesday as the upper wave exits but north winds in the Canadian airmass keep highs in the lower to middle 40s.
LONG TERM. (Tuesday night through Monday) Issued at 307 PM CST Mon Feb 17 2020
The Tuesday night into early Wednesday periods appear quiet with more high cloud streaming overhead downstream of the next upper wave digging southeast into the central Rockies. Reinforcing surface high pressure builds into the mid-Mississippi Valley as this occurs with dry/cold northeast winds developing as a more impressive upglide/frontogenesis scenario takes shape late Wednesday into early Thursday. 12Z runs continue to suggest the eastern end of precipitation will be over to near the CWA but have little doubt this will be a difficult to nail down low QPF/high coverage-type event. The cold air remains in place into Thursday with highs for Wednesday and Thursday only in the 30s. South winds return Friday into Saturday to bring temps back to near normal though a southern branch wave could impact the area via WAA precip as early as Saturday afternoon. Greater chances look to come around Sunday as the wave passe through, though this timing could easily be off as seen in some ensemble runs. At this point wintry precip accumulation potential looks low with the northern branch energy to the northwest keeping cold air intrusion in check.
AVIATION. (For the 06Z TAFS through 06Z Wednesday) Issued at 1051 PM CST Mon Feb 17 2020
Satellite showed an area of MVFR CIGS moving south towards the terminals before high clouds moved over. These clouds were eroding from the north as they moved south. So the expectation is for any MVFR CIGS to be short lived. With continued low level dry air advection, VFR Conditions are expected to prevail through the day Tuesday.

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.
