526 FXUS65 KREV 291920 AFDREV Area Forecast Discussion National Weather Service Reno NV 1220 PM PDT Sun Sep 29 2024 .SYNOPSIS... * Slight cooling expected Monday before temperatures rise well-above average through mid-week. * Locally breezy northeasterly winds are expected this afternoon into Monday morning. * A general cooling trend and some afternoon breezes are expected late next week, but latest trends favor only a slight cooldown. && .DISCUSSION... Look outside... that`s what you`ll be getting through at least mid- week! On a serious note, not too much has changed since previous forecast. Temperatures remain unseasonably warm today, with highs in the mid-upper 80s today across lower valleys of western NV and northeast CA and the mid-upper 70s for most Sierra valleys. A shortwave trough brushing by to our north today will sweep a modest dry cold front through the region, resulting in a minor cooldown on Monday, though only about 2-4 degrees cooler and still well above seasonal averages. This front will also bring breezy north to northeast winds late this afternoon into Monday morning, with strongest winds along mountain ridgelines as well as areas near the Oregon border. Expect peak gusts around 25-35 mph. The cooldown will be short-lived, as an anomalously strong ridge builds into the region by late Monday through Wednesday. Temperatures will climb well above seasonal averages, with highs maxing out on Wednesday around 10-15 degrees above average. Blended guidance is still holding steady on a 20% chance for breaking Tuesday`s record high of 93, and a 90% chance for breaking Wednesday`s record high of 90. The spread in solutions has narrowed finally for the latter half of this week, with a general cooling trend with increasing afternoon breezes as more zonal flow overtakes the western US. This cooling, however, will not really bring too much relief as temperatures are still expected to remain above average. High confidence still remains for the continuation of dry weather, with no precipitation expected through the entirety of this week. Whitlam && .AVIATION... Some enhanced north to northeast winds are expected late this afternoon into early Monday morning, mainly for areas near the Oregon border and the Basin & Range. Otherwise, great flying conditions expected as clear skies and generally light breezes prevail today into Monday. Whitlam && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$
