. AVIATION UPDATE .
SHORT TERM. (This evening through Wednesday) Issued at 321 PM CST Tue Dec 10 2019
As of mid-afternoon, the center of a 1030mb surface ridge was sliding southward out of the Dakotas and Nebraska. Looking aloft, water vapor imagery depicted a broad troughing pattern in place across the Midwest with a stream of moisture moving over the eastern US ahead of a 500hpa shortwave trough over TX. Closer to home, a mid level deck of clouds and associated light radar reflectivities was moving across north-central portions of the state. However, no evidence of precip was noticed on sfc obs given the very dry airmass in place. A few high resolution models are showing another quick moving batch of very light precip moving through the northwest flow over the CWA. Have kept POPS less than 15 percent with no mention of precip given low level dry air in place and lack of any obvious lift.
The surface ridge will continue southward tonight as another ridge moves out of Canada. In the meantime, lee cyclogenesis will occur in the Colorado Front Range tomorrow in response to an upper wave moving across the Rockies. Southerly flow will set up over the CWA allowing for low level WAA to commence. As a result, temperatures should be noticeably warmer tomorrow afternoon with highs forecast to reach the upper 40s to near 50 degrees.
LONG TERM. (Wednesday night through Tuesday) Issued at 321 PM CST Tue Dec 10 2019
In the long-term, conditions stay fairly settled until a more active pattern sets up during the weekend/early next week.
On Thursday, the surface low over CO will sweep northeast across western and northern KS with no impactful weather expected to occur here. Temperatures continue to moderate with highs in the low 50s for much of the area Thursday and mid 50s on Friday. A cold front is then expected to move through the area Friday night followed by the arrival of a much cooler airmass. The EC model is hinting at precip occurring behind the front in an area of weak ascent on Saturday. The going forecast is currently dry, but we will monitor trends for the possibility of introducing POPS on Saturday. Attention then turns to a system brewing over the western CONUS on Sunday. At this range, there is not good agreement between models regarding chances and timing of potential precipitation. As of right now, models show a surface low working across TX on Monday, which would place northeast KS too far north for the most favorable area of decent snowfall. Confidence in details should begin to increase as we move closer so stay tuned for updates to the forecast.
AVIATION. (For the 00Z TAFS through 00Z Wednesday evening) Issued at 512 PM CST Tue Dec 10 2019
Water vapor imagery suggests the subtle upper trough axis is beginning to move east of the forecast area. This along with models showing mid level frontogenesis weakening and a relatively dry low level airmass still in place should allow VFR conditions to prevail. There remains the possibility for some LLWS overnight due to a strengthening low level jet after the boundary layer has decoupled.
