Area forecast discussion National Weather Service Memphis Tennessee 339 PM CDT Tuesday Jun 18 2013 Discussion... Currently...the weak cold front has moved just south of the forecast area along with most of the showers. Skies are clearing out as drier air...dewpoints in the middle 60s...filters in on light northerly flow. Temperatures range from the upper 70s where clouds have hung on the longest to the middle 80s in Jonesboro. Tonight through Thursday night...upper level high pressure will start to build across the Southern Plains leaving the midsouth in weak northwest flow aloft. Surface high pressure will track across the Great Lakes and Ohio Valley. Surface winds will generally be northeast gradually shifting to the east with surface dewpoints in the 60s. Daytime highs will be in the lower 90s with lows in the 60s to lower 70s in Memphis. Expect the weather to be rain free with a good deal of sunshine. Patchy fog is possible later tonight. It is not out of the question that upper level disturbances moving through the northwest flow aloft could produce a few showers and thunderstorms from Missouri into the midsouth during this period though not confident enough to mention at this point. Some shower/thunderstorm development is already occurring just north of the I-44 corridor in central Missouri this afternoon. However this activity should die with loss of heating this evening and it will be moving into a less favorable environment as it heads south. Friday through Tuesday...upper level high pressure will build over the region. Expect mostly rain free and seasonably warm conds with highs in the lower 90s and lows in the upper 60s to lower 70s. Southeast winds will prevail Friday and Saturday with dewpoints remaining in the middle 60s. By Sunday into early next week winds turn more southerly with dewpoints climbing to around 70. This should allow for isolated afternoon showers and thunderstorms sun- Tuesday. Sjm && Aviation... 18z taf cycle Current MVFR conditions at kmem and kmkl should improve to VFR levels by middle-afternoon with VFR conditions continuing at kjbr and ktup. A few showers continue to move over extreme southeast sections of the forecast area and should exit the region by late afternoon.
