SYNOPSIS

Chilly and showery conditions continue through tonight as a low pressure moves eastward across the Great Basin. A drier weather pattern then returns for this week, with temperatures returning to near mid-April averages on Monday. The remainder of the week will bring further warming with afternoon highs 10 to 15 degrees above average.

DISCUSSION

Key points:

* Cool and showery conditions continue this evening then wind down overnight.

* A drier weather pattern will return for this week, with a longer period of warmer spring conditions likely.

Satellite/radar imagery currently shows a diminishing area of light showers across northeast CA and western NV mainly from I-80 northward. The high resolution guidance develops convection along the NV/OR border that evolves into a band of steadier rain/snow marching southward across northern Washoe County and northeast CA through late afternoon. While high April sun angles will prevent much snow accumulation on roads, there could be short periods of slushy conditions during heavier snow rates on higher elevation road segments such as Cedar Pass, US-395 in northeast Lassen County, and several CA state highways north and west of Susanville.

As we get closer to sunset, leftover showers from this precip band move across the Tahoe basin and near I-80 in far western NV but travel impacts will be minor with most shower activity ending prior to midnight.

The upper low responsible for this precip will then exit to the east across the Great Basin early Monday, giving way to a ridge of high pressure near the west coast. This ridge will remain rather flat across CA-NV in response to another trough moving along the US-Canada border through midweek, before amplifying slightly by late week/next weekend. Even with the flatter ridge, we'll still be in an overall dry pattern and be able to shake off this recent chilly spell. By Monday, highs are expected to rebound into the lower-mid 60s across most lower elevations, with 50s for Sierra communities and areas near the OR border. Further warming is anticipated as the week progresses, although this will be a slower process for areas well north of I-80, due to the fringe effects of the trough along the US-Canada border.

For late week into next weekend, the majority of the ensemble guidance favors daytime highs about 10-15 degrees above average, well into the 70s and possibly reaching 80 for lower elevations, with mainly 60s for most Sierra communities. This will bring increased melting of the Sierra snowpack, with faster cold flows on rivers and streams. Also with these warmer conditions, we could see some PM cumulus buildups and possibly a couple of brief showers if a weak upper disturbance moves overhead, but this potential is only in the 5-10% range at this time.

AVIATION

* Isolated-scattered showers will continue into this evening, favoring the Sierra and northeast CA where occasional MVFR conditions and terrain obscurement will persist around showers.
Thunder chances will remain low and mainly near the Oregon border (15% chance). Showers will gradually end overnight as the upper low begins to shift towards the eastern Great Basin.

* Breezy W-NW winds will continue, especially north of I-80 and along the eastern Sierra, with gusts mainly in the 20-25 kt range through 03Z then decrease overnight. FL100 winds will shift to more northerly at 25-35 kt tonight and Monday morning on the back side of the upper low, bringing areas of turbulence.

* Cloud cover will hang around through much of tonight but there is a 20% chance that enough breaks may occur for some patchy freezing fog 10-16Z at KTRK. The freezing fog potential at KTRK increases to above 70% for Tuesday AM, with skies and light winds producing conditions more favorable for fog formation.

* A drier and warmer pattern is setting up for the week ahead with shower chances very low and PM wind gusts generally 20 kts or less at the main terminals.
