As of 9pm...the surface trough is along the southern periphery of the cwa and will continue to shift south this evening. Convective storms will also continue to shift south with this front. Easterly flow has taken over. Guidance is suggesting a low cloud deck will develop...along with patchy fog late tonight. Lows will be in the mid to upper 60s. Low clouds and patchy fog early Saturday should break for sun over most of the area and highs will return to the low-mid 80s. However, with drier air pushing in from the north, it should be more comfortable than Friday.

&& .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... Ridge builds across the area aloft on Sunday then gets pushed east of the area by a shortwave on Monday. At the surface...high pressure will shift east of the area on Sunday but a tongue will extend southwest across the region. By Monday the next cold front will be approaching from the west. The high will promote possible patchy fog early Sunday...otherwise sunshine will dominate and it will be slightly warmer than Saturday. By Monday clouds will increase and showers and thunderstorms will spread into the area by afternoon. Will need to watch any severe threat. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... Seasonably warm and humid conditions are expected Monday in southerly flow. A cold front will move in from the west during the day and may trigger showers and thunderstorms. Shear looks like it won`t be as impressive as with recent events, but still decent veering (southerly at the surface to westerly at 500 MB). The front may get hung up over eastern parts of the area Monday night into Tuesday before weakening. High pressure will bring a return to dry weather briefly Tuesday night into Wednesday before another system approaches late in the week. && .AVIATION /02Z SATURDAY THROUGH WEDNESDAY/...
