688 FXUS66 KOTX 091729 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1029 AM PDT Tue Oct 9 2018 .SYNOPSIS... An area of low pressure moves through the region today with rain, cool temperatures, and breezy winds. Light snow above 5000 feet could lead to slick travel over Sherman Pass and North Cascades Highway early this morning. Precipitation tapers off this evening with breezy northeast winds overnight. More breezy north winds arrive Friday, otherwise expect mostly dry weather for the rest of the week with a slow warm up into the weekend. && .DISCUSSION... Morning update to address some spotty decaying shower activity located on the northwest edge of the departing low pressure system. This convection is showing a decreasing/weakening/eroding trend with suspicion that daytime heating is eroding the elevated layer upon which it is being forced upon. Have opted to update the forecast to account for its presence with a minor mention of isolated sprinkles between 11am and 2 pm today. /Pelatti && .AVIATION... 18Z TAFS: Area of low pressure that will make a slow exit to the south and east is taking the precipitation with it. Some residual showers are moving counterclockwise on the northwest edge of the low and the elevated layer upon which it is being forced on is being eroded with daytime heating so have opted to show the decreased precipitation rates resulting from the decaying activity as sprinkles. Some MVFR ceilings and visibilities remain at times this morning near this precipitation, otherwise Wednesday morning some patchy fog may linger in outlying areas that are better sheltered from the drier air being brought down by the northeast wind that will prevail tonight into tomorrow morning. /Pelatti && .PRELIMINARY POINT TEMPS/POPS...
