SYNOPSIS. Nice summery day for most of the Interior today and tomorrow. Isolated thunderstorms east of Fairbanks and the Elliott/Dalton Highways this evening, then mainly along the AlCan Border Tuesday. Temperatures warming into the 70s to mid 80s this evening and Tuesday in the Interior. Will remain cool on the West Coast as a weather front will continue to bring clouds and showers to the area through Tuesday. The Arctic will see a mix of weather with showers from Utqiagvik west, and some clearing to the east. Temperatures in the Arctic will be warmer, but warmest east of Utqiagvik and in the Plains where temperatures will rise into the 60s and 70 over the next couple days.
Models . Not much new guidance to work with today so will lean on the previous solutions for the forecast since they showed good agreement through the short term and the midrange yesterday. Convective indicies are fair to good the next couple day with most activity east of Fairbanks and the Dalton Highway. Lifted Indicies range from +1 to -3, and CAPE values range up to around 1200 J/kg. A wave moving around a low in the Gulf of Alaska will bring increased thunderstorm activity by late Wednesday into Thursday, but with the lack of new model information will limit it to scattered for now. Going with an equal blend of the solutions we have, but will be filling in some of the holes to capture the isolated to scattered thunderstorms and showers to the east. 850 hpa temperatures are still on the rise and will be around +16C at their warmest Tuesday. Will need to make some local adjustment to the winds, primarily south of Delta Junction to capture the thermal low kicking the winds up this evening.
Aloft . At 500 hpa . Ridging continues to build with a 564 dam high over Denali and a 564 dam high over the Upper Yukon Flats. Troughing to the west with a 533 dam low over the Gulf of Anadyr that is moving north, and a 541 dam low that is 200 nm south of Dutch Harbor moving southeast. To the east of the ridge a 551 dam low that was over the Northwest Territories is moving northeast, and a 552 dam low is 150 nm west of the Queen Charlotte Islands. Tuesday afternoon the ridging over the state will be anchored by a 567 dam high over Chalkyitsik with ridging pushing southwest over St Matthew Island. The low that was over the Gulf of Anadyr will be 300 nm northeast of Wrangel Island at 528 dam, a 551 dam low will be southwest of the Gulf of Anadyr, a 546 dam low will be over Adak, and 540 dam low will be 400 nm south of Chignik, while the low near the Queen Charlotte Islands will be 150 nm west of Sitka with an inverted trough extending northeast over Watson Lake YT. Wednesday afternoon the will be moving off to the northeast with the 567 dam high over the Northwest Territories and ridging extending west over the Brooks Range and Chukchi Sea, and southwest over the Lower Yukon Delta and the Pribilofs. The low that was over the Western Arctic will be over the Northern Beaufort Sea as it moves east over 80N. Weak troughing will persist over the Western Bering Sea, as the low near Adak moves southeast to 200 nm southeast of Dutch Harbor while the low south of Chignik will move to 600 nm south of Cordova at 550 dam and the low near Sitka will move over the Central Gulf of Alaska at 557 dam. The inverted trough will rotate east to lie over Tok to Dawson YT, and a second trough will move to lie from Yakutat to Carmacks YT At 850 hpa. Large dome of warm air has moved over the Eastern Brooks Range, and the Central and Eastern Interior with temperatures near +14C from Fairbanks east. The -10C isotherm lies from Kaktovik to Anaktuvuk Pass to Ambler to McGrath and south of the Alaska Range today. By Tuesday afternoon the +10C isotherm will lie from Deadhorse to Bettles to Nikolai and south of the Alaska Range with temperatures near +16C over the Eastern Interior.
Surface . Ill defined pressure pattern over the state with high pressure to the northeast with a 1021 mb center near Banks Island, a 997 mb low moving north into the Chukchi Sea with the associated weather front moving over the West Coast. A 1000 mb low is 300 nm south of Sand Point, with a 1018 mb high 300 nm south of Prince William Sound, and a 1011 mb low 200 nm southwest of Sitka. Weak leeside troughing north of the Alaska Range is associated with thermal trough that also extends north along the AlCan Border. Tuesday afternoon not much change in the pattern over the state as the thermal trough remains along the AlCan Border. The high near Banks Island will move east of the island, while the low in the Chukchi Sea will be 300 nm northeast of Wrangel Island. Weak high pressure will move into the Northeast Bering Sea with low pressure over the Eastern Aleutians and the Western Alaska Peninsula.
Arctic Coast and Brooks Range . Showers from Utqiagvik west tonight as a low moves north across the Western Arctic tonight, then east across the Northern Arctic Tuesday. Isolated thunderstorms again today in the Eastern Alaska Range. Winds along the coast generally east at 5 to 15 mph will become southwest at 10 to 20 mph from Utqiagvik west Tuesday. Winds inland will be variable to 10 mph. Inland temperatures much warmer with less clouds so the plains will see highs in the 60s to around 70 today and in the mid 60s to mid 70 Tuesday, while the Brooks Range see highs in the 60s today and Tuesday. Along the coast highs will be in the 40s today and upper 40s to around 60 Tuesday with the warmest temperatures east of Utqiagvik.
West Coast and Western Interior . Showers will continue, mainly along the coast, but may move into the Upper Noatak and Kobuk Valleys as the front continues to drag north, then east across the Arctic. The Middle Yukon and Upper Kuskokwim Valleys will generally be dry, but with some clouds. High temperatures continue warming in those inland areas and will be in the low to mid 70s Monday and the mid to upper 70s Tuesday. Along the coast high will only reach the 40s to around 50 with the cloudy conditions and showers today and Tuesday, but warm to mostly 50s by Wednesday. On St Lawrence Island temperatures will be in the mid 30 to around 40. Winds picking up a bit along the coastal areas to southeast at 10 to 20 mph becoming southwest Tuesday, while winds in the inland areas will be 5 to 15 mph.
Central and Eastern Interior . Isolated to scattered thunderstorms and showers this evening mainly east of Fairbanks and the Elliott/Dalton Highways. Mostly clear in the Central Interior. Much the same Tuesday with most thunderstorm activity confined to areas near the AlCan Border. Winds generally light and variable, but some south winds kicking up this evening to the south of Delta Junction could produce near Red Flag Conditions in combination with the warm and dry day we have. Those winds will diminish late this evening. Thunderstorms may produce small hail and brief downpours. High temperatures in the upper 70s to mid 80s today through Wednesday. Overnight lows will be quite warm as well with lows across most of the area in the 50s.
Extended forecast for days 4 to 7 . Ridging aloft hanging on over the northern half of the state with warmer and drier conditions and isolated to scattered thunderstorms and showers in the afternoons and evenings. Troughing to the south extends from the Aleutians to the Gulf of Alaska. As the ridging holds a wave will move around the low in the Gulf over the Alaska Range and southern Interior Friday, with a low moving over the southwest mainland Saturday. Temperatures will be warming on the Arctic Coast and Plain with slightly cooler temperatures south of the Brooks Range.
Fire Weather. Isolated to scattered thunderstorms and showers this evening mainly east of Fairbanks and the Elliott/Dalton Highways, with showers continuing on the West Coast. Winds generally light and variable from the Nulato Hills east, but some south winds kicking up this evening to the south of Delta Junction could produce near Red Flag Conditions in combination with the warm and dry day we have. High temperatures in the 70s to mid 80s today through Wednesday. Overnight lows will be quite warm as well with lows across most of the area in the 50s. Overnight Relative Humidity recovery will be poor through Thursday. A wave moving around a low in the Gulf of Alaska will bring increased thunderstorm activity to the Central and Eastern Interior Wednesday and Thursday.
Hydrology. Yukon River in Canada is near bankfull, but the gage at Eagle remains well below action stage. Most interior rivers have diurnal rises and falls as snowmelt continues but they are running below normal. In the Arctic there are no issues.
