The cool moist upper trough shifts east today in a North-North Easterly flow aloft. The freezing level will creep up from 2000 meters and hover in the 2500 meter range rising back to 3000+ meters Tuesday into Wednesday. A mix of sun and cloud for today with the slight chance of some isolated showers as weak ridging builds into the area for Tuesday. Mostly cloudy for Wednesday as a series of weak upper troughs push through into Friday. Weak ridging likely Saturday with unsettled weather expected again Sunday. Early next week will likely see an unsettled day Monday with weak ridging by Tuesday, many changes could happen by then but we are certainly seeing unsettled weather with cooler temperatures for the next week. Heat wave could be gone until next summer!!??  Guesstimates: 0-trace by Tuesday am, 0 mm by Wednesday am, 0-1 mm by Thursday am, trace-3 mm by Friday am, trace-1 mm by Saturday am, 0 mm by Sunday am.
