High pressure builds in from the northwest Monday and remains over the area for much of the upcoming week. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Shras/possible tstms shift to the coast late this evening/after midnight...then end late. Partial clearing expected wrn portions as winds shift to NW (post cold front) and drier air begins to arrive.

Surface ridge axis locates along the coast Thursday, as surface winds become south to southeast. Further modification of dewpoints and temperatures expected, but dry conditions prevail. Daytime temps warm into the mid to upper 80`s acrs the area (cooler again nearest the coast). Medium range guidance is less amplified than 24 hours ago with a northern stream trough digging into the upper Midwest and Great Lakes region. The result is a slower and weaker cold front for late in the week. Have just slgt chc pops acrs extrm NW counties for Fri, with highs warming into the upr 80s to lower 90s thanks to southerly winds. The front progged to now drop into the area during Fri, but with upper level high pressure over the SE states, it looks like the front will dissipate ovr srn portions of the region. High pressure will then bld fm the Grt Lks and OH valley ewrd into the ern Grt Lks and srn New England Sat thru Sun. This will result in more dry wx with highs ranging fm the mid 80s to lower 90`s. && .AVIATION /06Z MONDAY THROUGH FRIDAY/...
