Marine Weather and Tide Forecast for Ponderay, ID

SYNOPSIS
The Inland Northwest returns to a dry period through Thursday.
Patchy valley fog and temperatures below freezing could result in slick roads each morning. A more active weather pattern returns late Friday into the weekend, with mountain snow and a mix of rain and snow in the valleys. Colder temperatures, with lowering snow levels for the latter half of the weekend into next week, will bring the potential for light lowland snow accumulations.

DISCUSSION
Through Thursday: Weak ridging will lead to dry and generally benign conditions. Any impacts are expected to be limited to those from areas of fog development Thursday morning. Areas most likely to see fog are sheltered valleys and those adjacent to bodies of water. With low temperatures dipping below freezing again, patchy black ice could affect the morning commute.

Friday through Sunday: Forecast turns more unsettled through this period. Expect areas of light precipitation beginning Friday night, mainly in the form of mountain snow (primarily the Cascades) and a mix of rain and snow into the lowlands. Rain and snowfall totals are expected to be light, though Stevens Pass and Lookout Pass are both likely to exceed 2 inches of snowfall through the weekend. Any rainfall across the lowlands has the opportunity of for freezing overnight on area roadways.

Monday through Wednesday: Extended range models and the CPC's 6-10 Outlook favor cool conditions with occasional precip.
While confidence in the timing of any particular feature remains low, we should anticipate a wintry mix of precipitation to impact much of the Inland Northwest thru the period. /KD

AVIATION
00Z TAFS: Reduced flight categories possible overnight/early tomorrow morning as inversions and calm winds allow areas of fog to develop. Otherwise, VFR conditions under occasional high clouds are expected through the forecast period.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence for primarily VFR conditions through the period.
The exception will be mainly for terminals around water bodies which could see shallow fog late tonight/early tomorrow morning.There is a chance flight categories end up worse than what is forecast in the TEMPO groups. However, expect conditions not far off from what occurred last night/early this morning with no change in airmass.
