Broad western ridging will result in an unusually warm week as daytime highs climb into the upper 50s to mid 60s. Tuesday through Thursday look to be the warmest days of the week, when of which we`ll more than likely tie/set new daily record highs. On Tuesday, Reno-Tahoe Int`l Airport has an 85% chance of breaking the daily record high of 65F. The only other weather item to note for this week is morning haze and degraded air quality across lower urban valleys as inversions strengthen, but daytime heating should help disperse hazy skies in the afternoons. The blocking pattern that has kept us dry over the last couple weeks looks to finally dislodge towards the middle of the month, which may usher in more unsettled weather beginning the week of December 15th. Precipitation and wind potential increases as early as this upcoming Sunday, followed by a more earnest increase between December 16- 18th. As of now, there isn`t a convincing signal for strong winter storms, but it`s still an encouraging trend for us to see much needed rain and mountain snow during the second half of the month. -Salas && .AVIATION... Minimal weather concerns this week as high pressure maintains VFR conditions and light breezes. Periods of FZFG and IFR/LIFR conditions are possible at KTRK between 12Z and 16Z. Slantwise visibilities may also be reduced each morning due to hazy skies. -Salas && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$
