Weather West https://validator.w3.org/feed/docs/rss2.html Warm subtropical system to bring heavy New Year’s rain to SoCal before a somewhat quieter pattern takes hold by mid January “Warm West/Cool East” dipole to develop over North America in late January; mostly dry/warm conditions lead to record-low Western U.S. snowpack “The Big Melt” has arrived as early season heatwave spikes flood concerns; Cut-off low to bring cooling trend but also possibly thunderstorm outbreak next week Extraordinary and prolonged March heatwave to break records and decimate mountain snowpack across U.S. Southwest, including much of California Following a cool and wet October, a much warmer and drier November to come across California Major storm to bring high risk of debris flows in SoCal wildfire zones, with some flood risk elsewhere Following a whiplash transition from record warmth to very heavy mountain snowfall in California, yet another swing back toward anomalous warmth (first damp, then dry) Wild weather week possible in California as humid heat transitions to potential dry-to-wet thunderstorm outbreak thanks to tropical storm remnants After anomalous late Oct warmth, a sooner-than-expected shift back toward wetter conditions in (at least) NorCal A chillier and windier solstice with increased lower elevation fire risk; All signs still point to more widespread and anomalous heat later in summer As progressive ridge-trough pattern shifts toward more persistent ridging, rising heat in CA and the Southwest likely in late May An active pattern to continue across California, with mainly beneficial precipitation through mid-Mar An unusual weather pattern to bring extreme British Columbia/PacNW heatwave, with lesser CA heat (and the potential for a few surprises) Warm, wet atmospheric river to soak NorCal, w/mostly modest flood risk; SoCal likely to see at least some additional rain Mild and occasionally unsettled spring conditions to persist into mid-May, with hotter/drier conditions still likely thereafter Widespread rain in SoCal to temporarily alleviate fire concerns by Sunday; SoCal drought still likely to expand rest of winter More inland heat before late July reprieve amid record-hot summer to date & escalating Western wildfires A wet and stormy week ahead in California, with substantial SoCal flood risk and initially warm Sierra rain transitioning to very heavy snow Cold storms headed for CA, including rare blizzard conditions in Sierra Nevada Fri-Sat Following historic wildfire disasters in Southern California, a statewide dry spell intensifies and extreme fire weather conditions persist in the south Southern California weekend storm looking increasingly powerful, with growing flood threat for LA Basin & beyond Frequently Asked Questions Hotter temperatures ahead for California heading into mid-July as fire season heats up Sudden shift to very wet conditions in NorCal with strong & very slow-moving atmospheric river poised to soak region in coming days; flooding likely in north Unusually hot weather returns to the West, with major heatwave & fire weather escalation after Labor Day Major autumn heatwave to continue streak of record heat in interior Southwest; Warm to hot in California for foreseeable future After hottest July on record across most of California, more modest heat to come through mid-Aug (plus some monsoonal thunderstorms) Long-duration and in some cases record-breaking heatwave across much of CA in early July Contact Complex weather pattern to bring notable early-season heatwave across West, including parts of California Mild spring pattern to continue across California through early May. Plus, thoughts on summer to come… Colder system will bring widespread CA rain this weekend, with modest flood risk SoCal Pair of major “Pineapple Express”-type atmospheric rivers to affect California Wed-Mon; elevated flood and wind risk (especially from storm #2) Climate change is narrowing and shifting prescribed fire windows in the western United States Fall-like weather pattern for CA as El Niño continues to strengthen; Odds of a second consecutive wet winter rise (though with caveats!) Stronger cold storm this weekend in NorCal, then warmer and quieter weather to follow. Plus: seasonal outlook and El Niño update… Major early-season storm to affect CA by mid-Nov; Plus, new thoughts on implications of still-strengthening El Niño for CA winter After frustrating false starts, strong indications of a major Pacific jet extension & active pattern by late Dec Archives Warm and “wet north/dry south” pattern to continue in California Major and prolonged heatwave develops by this weekend over CA & Southwest; Record temperatures possible in San Joaquin Valley Heat, humidity, and some thunderstorms to come as cut-off low sets up shop south of blocking ridge. Plus, some brief thoughts on the Maui wildfire disaster. Potentially historic summer storm event to unfold in SoCal this weekend as weakening Hurricane Hilary threatens to move ashore as tropical storm–causing severe flood risk in SE desert region Active, wetter and cooler pattern to return to CA during late March Significant, though not extreme, heatwave in California for the holiday weekend Additional storms to bring renewed flood risk to parts of CA Unusually unsettled June pattern this week, and relatively cool pattern to continue through mid-month A (relative) mid-August reprieve for CA, but peak of fire season may be yet to come Another swing of the precipitation pendulum in NorCal; Meanwhile, Santa Ana winds & wildfire risk in SoCal Much warmer conditions and mountain thunderstorms return to CA as extreme blocking pattern develops over western Canada
