An upper low across northwest KS will slowly drift northeast into southeast NE by 12Z SUN. Most of the ascent ahead of the upper low will remain north of the CWA but there may be enough lift for occasional showers and perhaps an isolated thunderstorms. If there are breaks in the overcast highs could be slightly warmer. Tonight, as the upper low moves northeast across the far norther counties of the CWA into southeast NE there could be some residual moisture that wraps around the vertically stacked surface/850mb/H5 low which could cause isolated showers to develop southward towards I-70 after midnight. By Sunday, the upper level low will be located just northeast of the area keeping showers limited to areas north of I-70 through the afternoon.
645 AM CDT SAT APR 30 2016 CURRENT SATELLITE WATER VAPOR IMAGERY SHOWS THE UPPER-LEVEL LOW PRESSURE SYSTEM CENTERED OVER WESTERN KANSAS.

Have also increased or continued pops Monday into Monday night with plenty of mid level instability to the north of the stalled cold front in Kansas.
The upper level low continues to slowly migrate north into NW Washington today. Offshore flow will be spread across the east side by morning with a thermal trough continuing to deepen along the coast. The thermal trough moves inland on Monday bringing a slight warming from today.
Current water vapor imagery and RAP upper air analysis indicate that the upper level ridge across the central CONUS is expanding further to the east. For today, expect upper level height rises with subsidence aloft as the ridge continues to expand to the east. This will lead to mostly sunny skies with temperatures a bit warmer than yesterday due to the increase in upper level heights. 8 inches today, with the lower end being near the minimum value observed for mid-June. Dry conditions will continue overnight as high pressure becomes established across the Carolinas.
The mid and upper level inverted trough of low pressure axis has shifted into Southeast to North Central Texas and shifted the previous convection West.

Midlevel warming continues and will be reflected at the surface today with temperatures remaining well above normal and a few degrees warmer than yesterday. A few changes Monday with the first being the high temperatures that will now be reaching near record territory. Models showing a rather meager fetch of moisture rotating around the high pressure that may be just enough to get some convection going.
336 AM CDT SUN JUN 19 2016 High pressure from the Ohio Valley west into eastern Kansas will gradually move off to the east today. This will send the cold front further south tonight slowly into southern Nebraska late tonight. This will yield highs in the lower to middle 90s. Lows tonight will range from the upper 60s to the lower 70s. Rather fast upper flow over the northern states and upper high over the south remains to dominate the these periods. Slight warming ahead of the front Monday should bring a warmer day, with heat index values likely breaching 100.
A vast and sprawling upper level ridge, centered over the Intermountain West, will be gradually having more influence on our region's weather through the short term period. But the usual drying and heating sensible weather trends correlated with this synoptic evolution will be delayed a bit in our forecast area considering temperatures should be a little cooler than yesterday and at least some rain chances will remain for most. The main driver of conditions today will turn out to be not too shabby southeast low level flow continuing in the wake of the inverted trough sliding west past our region yesterday. Between late tonight through midday Monday the moderate southeast low level flow regime will be breaking down and that evolution, combined with the aforementioned building ridge, will decrease precip chances.
258 AM EDT SUN JUN 19 2016 High pressure remains in control through Monday, resulting in cool nights and warm afternoons along with low humidity.
This cold front will be the primary focus for convection late this afternoon into the evening, with best upper forcing from jet dynamics and PV advection remaining up on the international border.
