.SYNOPSIS... Not a whole lot of change to the ongoing forecast. The bulk of the weather will be unimpactful, but there will be some localized spots that experience minor impacts. One of which will be in the Interior tonight through tomorrow where rain and snow will result in slick travel conditions. The other spot will be along the coast where a series of lows brings rain and wind as well as some high surf and wave run up this weekend.

.KEY WEATHER MESSAGES... Central and Eastern Interior... - Snow and rain ending this morning, only to be replaced by more snow and rain this evening through tomorrow.
- Snow ratios will be very poor everywhere, resulting in wet, slushy accumulations. Highest accumulations of 3 to 6 inches will be in the White Mountains while everywhere else may see 1 to 3.
- Winds will be breezy on Friday, with gusts to 25 mph in Fairbanks and the valley, but up to 35 mph north/east.
- Snowfall will be rate dependent in the valleys, meaning heavier precipitation will cool the atmosphere, resulting in snow, lighter precipitation will allow for warmer air, meaning rain.
- Rain and snow ends tomorrow afternoon, with light rain and snow showers Saturday.
- Temperatures warm significantly this weekend as most, if not all, snow melts with widespread low to mid 50s by Sunday.
West Coast and Western Interior... - Persistent Bering Sea lows bring rain and wind everyday, or every other day for at least the next week. - A widespread 0.50 to 1.50 inches is expected for most spots on the coast and in the Interior with the heaviest coming Saturday into Sunday morning.
- Winds will be changing from the southeast/south this weekend to southwest next week. High water is likely along the coast with wave run up and water levels 3 to 5 feet above the normal high tide line this weekend and potentially next week as well.
- Temperatures will remain mild, in the upper 30s to near 40 north of the Seward Pen today, low 40s south of the Seward Pen, and warming into the upper 40s to low 50s for most by Sunday. Warmer weather persists into next week.
North Slope and Brooks Range.. - Rounds of rain and snow in the Brooks Range, but most of it is light with about 1 to 3 inches of snow through Sunday.
- Stratus and a few flurries or areas of light snow on the Slope with the highest chance of snow southwest of Point Lay, towards the Lisburne Peninsula. A couple inches of snow possible.
- Temperatures remain in the low to mid 30s along the coast with 20s to near 30 along the northern Brooks Range. Upper 30s to near 40 on the south side.

.FORECAST ANALYSIS AND DISCUSSION... A front is moving through the Interior with only light rain and snow over the Eastern Interior. Today remains chilly across the area and that sets the stage for another front brining more rain and snow this evening through tomorrow afternoon. Before we get there though, the front has to get through the West Coast and Western Interior. Expect rain for most of the coast and interior south/east of the Seward Peninsula today with mixed rain and snow north/east of the Peninsula. The low providing the precipitation will move on shore the southern Seward Peninsula this evening at 992 mb. Precipitation will move into the Central and Eastern Interior around or shortly after midnight. Most valley locations will be rain while the higher terrain above 1000-1500 feet will be predominantly snow. The rain in the valleys may go back and forth with snow depending on precipitation rates. The heavier precipitation will likely transition to, or mix with snow while lower rates will be rain. Heaviest snow accumulations will be in the White Mountains and towards Chena Hot Springs where there will be a slushy 2 to 4 inches.
A third low will move from south to north over the Eastern Bering at nearly 975 mb Friday night through Saturday. This will bring a round of gusty winds, rain and a surge of warmer temperatures to the West Coast and Interior. The strongest winds will be in St. Lawrence Island, but still only gusting to about 50 mph from the east-southeast. Otherwise, this rain and warm air moves into the Interior Friday night through Saturday with widespread rain and snow only above 5500-6000 feet. The rain moves out on Sunday leading to a much warmer day with isolated to scattered rain showers across the state.

.HYDROLOGY...No change from previous version. There is a bit of concern heading into this weekend and next week. Numerous rounds of rain and snow will move through Northern Alaska almost on a daily basis into the weekend and beyond. Through early next week, there may be widespread 1 to 3 inches of liquid precipitation across the area. Some of this will fall as snow, especially in the higher terrain, but most of it will melt as snow levels increase to nearly 5000-7000 feet across the Interior on Sunday. Next week will be mild with highs in the upper 40s or low 50s in the Interior, and this should melt a lot of the already accumulated snow across the higher terrain. If this happens, it would only add to the rain water entering the river system. At the very least, we should expect gravel bars to be covered but as of now, we are not anticipating any flooding.
&&
.EXTENDED FORECAST DAYS 4-7... The low in the Bering Sea will begin to move through the Bering Strait on Sunday, allowing the winds to diminish, leaving behind a few scattered showers for the West Coast. A warm front associated with this low will be making its way across the state, bringing scattered, mixed precipitation for the Interior and southern Brooks Range on Tuesday.
Tuesday and Wednesday will see another low move into the Western Bering and then repeat many of the same conditions as the one happening this weekend. It`s expected to strengthen rapidly in the Bering, but remain farther west providing some limits on the strongest coastal winds. However, as it passes through the Bering Strait on Wednesday, the Seward Peninsula and northwest North Slope are expected to see an increase in winds. Widespread rain with snow possible at higher elevations is expected once more.
Coastal Hazard Potential Days 3 and 4... Water levels will rise to 2-5 feet above the normal high tide line this weekend, particularly Saturday night into Sunday as south-southeast winds persist. The highest water levels (3-5 feet) will be along the southern Seward Peninsula and Norton Sound. Up to 2-4 feet is expected in the Yukon Delta, particularly Hooper Bay to Nunam Iqua. There will be wave run up as well as coastal erosion possible. Another stronger low will approach early next week with south/southwest flow and another chance for high water and even coastal flooding.
