.SYNOPSIS...High pressure aloft will bring warmer than normal
temperatures to the area through the weekend then temperatures
gradually cool next week leading up to Thanksgiving Day.

&&

.DISCUSSION...Upper ridge will continue to amplify over the area
today bringing another 4 to 9 degrees of warming today. Slightly
warmer tomorrow and Saturday, with highs running 5 to 12 degrees
above normal, depending on location. The upper ridge flattens
over the weekend which will start a gradual cooling trend on
Sunday that will continue into Thanksgiving Day. This cooling
trend is associated with an increase moister mid-high level zonal
flow over the area, which will lead to periods of partly to mostly
cloudy conditions and some daytime breeziness. Low levels remain
dry and any dynamics will remain north of the area. Can`t rule
out very slight chance, less than 20%, of light precipitation
across the White mountains Tuesday night into Wednesday.

the northeast portions of the forecast area Tuesday into Thursday of

next week. Min RH values will be 8-15 percent in the valleys and 10-
20 percent in the mountains through the weekend. Min RH values will
