/issued 909 PM CDT MON MAR 28 2016/ Low clouds are developing over the southern half of the CWA this evening, and will spread north during the overnight hours as the low-level jet intensifies. These strong winds atop the boundary layer will keep the boundary layer from strongly decoupling tonight, resulting in min temperatures 15-20 degrees warmer than what we experienced last night.

(Tuesday night through Monday) An upper trough over the Southwest U.
Strong upper low was noted digging south over eastern California, with an embedded wave ejecting eastward towards the desert southwest. Lee trough ahead of the system has created gusty south to southeast winds this afternoon at 12 to 15 mph sustained. Decent chance for precip Tuesday is centered over an area of broad, weak forcing near a warm front over southern Nebraska. In terms of temps, trended cooler than previous forecast given the thicker/lower stratus over north central KS where lower 60s are likely.
VFR conditions will persist given the higher ceiling heights anticipated. Much of the area will continue to see light-moderate southeast winds through the night with overnight lows several degrees warmer. The numerical guidance is now in good agreement in ejecting the western CONUS upper low/trough across the Plains midweek.
WATER VAPOR SATELLITE PICS SHOWING UPPER LOW OVER E-CENTRAL NV IS STARTING TO LIFT NORTHEASTWARD THIS EVENING. PRECIP SHIELD ON THE NORTHWEST PERIPHERY OF THE LOW WILL GRADUALLY WORK INTO S-CENTRAL IDAHO LATE TONIGHT IN CONJUNCTION WITH THE NORTHBOUND LOW.

/issued 213 PM CDT MON MAR 28 2016/ Strengthening sw flow aloft thru Wed will promote amplification of the low level thermal along with a farther ewd position. A cold front on Thur will keep high temps mostly in the U60s-L70s range. Another surge of cooler air is expected on Fri ahead of a mid level trof. Said mid level trof will be slow to move across and temps will remain coolish Fr-Sat (65-70). Warmer and thus drier Sun/Mon. Similar conditions Wed although windier, but cooler with RH/s trending a few percent higher.
MODEL AND PREVIOUS FORECAST THOUGHTS HAVE THE HIGHEST HUMIDITY VALUES ACROSS PARTS OF OUR EASTERN AREAS. VFR/SKC CONDS WILL PREVAIL AT HSV/MSL THIS EVENING AND OVERNIGHT AS HIGH PRESSURE CENTERED ACROSS THE GREAT LAKES BUILDS SWD INTO THE REGION. AS HIGH PRESSURE BUILDS INTO THE REGION. UPPER LEVEL RIDGING WILL MOVE IN FROM THE WEST DURING THE DAY ON TUESDAY.
