Area Forecast Discussion National Weather Service Sacramento CA 218 PM PDT Mon Apr 8 2019 .SYNOPSIS... Wet weather will gradually spread southward across the region late today and into tonight with most of the precipitation falling over the northern portion and mountainous regions. Thunderstorms with heavy rain remain a strong possibility over Shasta County this afternoon and evening potentially leading to flooding issues. Showers will decrease by Tuesday evening with dry weather expected Wednesday. Another system may bring some showers to the mountains Thursday. && .DISCUSSION... The forecast remains on track today as an upper level trough advances towards the west coast. Rain has been falling over the northern most areas of California so far, but will gradually spread southwards throughout the rest of the day and into the evening and overnight hours. Model guidance continues to trend towards thunderstorm activity for the northern half of the CWA, primarily over the Shasta County area. The HREF and HRRR ensemble continue to point toward the potential for strong thunderstorms with the main threat being heavy rain. This could lead to potential flash flooding given the saturated soils, deep available moisture, PWATs from local soundings, and strong south/southeasterly low- level inflow/ convergence. The latest HREF continues to highlight a high potential (> 50%) for hourly rainfall rates exceeding 0.5-1.0 inch an hour, and their ensemble even shows non- zero chances for 6 hour amounts to exceed 3 inches into this evening. Hail and a brief tornado remain possible, but given the convective ingredients and current cloud cover, confidence has lowered on these hazards. Moving on to the snow portion of the forecast, it continues to look rather unimpressive as snow levels will remain high throughout the rest of today. However, once the cold front moves through early Tuesday morning, snow levels are forecast to lower to around 5000 feet. Thus a few inches of new snowfall accumulation will possible across the higher passes before showers taper off late Tuesday. Behind this trough, we'll have a brief period of dry but breezy weather as high pressure builds over head on Wednesday. Models then show a "slider" type system slipping over the ridge. This could bring some showers to our mountains on Thursday. && .EXTENDED DISCUSSION (Friday THROUGH Monday) EFP forecast begins with a low pressure system from the Aleutian Chain spilling over the neutral to positively-tilted Ern Pac ridge and diving Swd across Wrn Canada the first half of this week, and then the Pac NW and NV by the end of the week. Precip over Norcal (mainly the Sierra) expected to come to an end early Fri, but pressure rises in the wake of this system will create those annoying strong, gusty Nly winds right during allergy season. WAD (wind advisory) criteria may be met. Strong Wly flow over the Pac creates a very progressive wx pattern over the Ern Pac and Noam with none of the trofs/ridges establishing a blocking pattern. This continues a series of low pressure systems from the GOA (Gulf of AK) moving through the Pac NW and Norcal bringing chances of precip to our CWA. This is where the daily model runs have difficulty in keeping up with the timing of the individual systems, thus forecast confidence is low on the details of each system. There is reasonable agreement that the next system will affect our CWA from N to S late Sat into Sun, with much less certainty for Mon and Tue. With the RMOP for 5H heights trending slightly higher then, we could be dealing with the drier ECMWF solution than the wet GFS solution. The RMOP would give credence to the ECMWF 5H pattern with W or NWly flow over Norcal than the deep 5H cyclone the GFS develops off the Pac NW coast late in the period. JHM && .AVIATION... Pacific front moving across Norcal during afternoon with thunderstorm lines/short segments developing behind the front during afternoon and evening hours thru 03z. Convective activity moving Ewd into the higher elevations of the W Slope Sierra til 07z. Mostly VFR conditions in the Vly except for MVFR/IFR conditions at times in the northern Sacramento Valley due to +SHRA/+TSRAGS. Developing widespread MVFR conditions over the W Slope Sierra with local LIFR conditions in precip obscuring higher terrain. Sly wind gusts 15-25 kts continue across the northern half of the Sacramento Valley through 03Z with gusts to 30 kts, and winds over the southern Sacramento and northern San Joaquin Valley gusting to around 20 kts thru evening. Behind front, drier NWly flow will return VFR conditions to Norcal on Tue. && .STO WATCHES/WARNINGS/ADVISORIES... Flash Flood Watch until 9 PM PDT this evening for Burney Basin / Eastern Shasta County-Mountains Southwestern Shasta County to Northern Lake County-Northeast Foothills/Sacramento Valley- Northern Sacramento Valley-Shasta Lake Area / Northern Shasta County-Western Plumas County/Lassen Park. &&
