(Today through Thursday) Issued at 320 AM CDT Tue Apr 17 2018 Next storm system to impact the area will be moving out of the northern Rockies and onto the western high plains today. No weather ahead of this system today other than a bit warmer temperatures for the area. Tonight the models are fairly close in tracking the surface low from western Kansas into north central Missouri while the upper trough swings to the northeast across the mid Missouri Valley and becomes negatively tilted over the area by Wednesday morning. Strong dynamics will be associated with this system and although moisture will be limited initially it does increase quickly after 06Z. Chance of thunderstorms for southern parts of the area look to be limited until later in the evening with a strong cap indicated in forecast soundings prior to that time. A few elevated storms are possible during the evening in the south with rain changing to freezing rain and snow in the far north after 06z. With the fast movement of the storm system the freezing rain is expected to result in limited icing before changing over to snow there in the far north. Snow accumulations of one to two inches are expected by Wednesday morning with up to an additional inch possible during Wednesday morning. In the south, pockets of moderate to heavy rain will be possible Tuesday night from southeast Nebraska into southwest Iowa. Gusty northwest winds will also move into the area behind the system Wednesday morning as the snow begins to move east of the area and continue through the afternoon. Despite the snow and northwest winds, temperatures are forecast to climb toward 40 degrees in the north Wednesday afternoon. Winds diminish Wednesday night with skies becoming partly cloudy as the system continues to rapidly eastward. Mostly sunny and warmer conditions are expected Thursday as upper riding moves over the region. .LONG TERM...(Thursday night through Monday) Issued at 320 AM CDT Tue Apr 17 2018 Another strong weather system is forecast to move out of the southern Rockies and across the southern plains Friday night through Sunday. This will bring a chance of rain to the area during this time with the more active weather expected to stay south of Nebraska and Iowa. Temperatures will be closer to normal for this time of year during this time.

(For the 12Z TAFS through 12Z Wednesday morning) Issued at 555 AM CDT Tue Apr 17 2018 Look for VFR conditions today with easterly winds. Conditions will deteriorate to MVFR and possibly IFR tonight, especially after 10 pm as precipitation develops. Highest chance for snow and IFR conditions will be at KOFK. East winds will turn to northeast and then north tonight as low pressure tracks from KS to southern IA/northern MO.
