Storms look to bring scattered showers to the area

By  | 

ANCHORAGE (KTUU) - While under partly cloudy skies Tuesday Anchorage warms to near 60 degrees.

There is storm energy easily seen on satellite imagery as a band of sun energy-producing clouds stretching across the southern Kenai Peninsula. This system has been pushing up Cook Inlet since yesterday afternoon and will bring widespread showers from the central Kenai Peninsula north over the Mat-Su Valleys through the first half of Tuesday. The winds across Turnagain Arm will also increase from the southeast overnight as this trough moves through. Late Tuesday into Wednesday is when things get a bit more complicated. Models are still struggling with the movement of a low-pressure trough across the northern Gulf that looks to spin up a low-pressure system as it gets some upper-level support from some storm energy lifting north across the Gulf that could bring rain to us again on Wednesday.

By late Wednesday into Thursday, all of these storms look to get absorbed into a much larger and stronger frontal system attached to a deep low in the Bering Sea feeding tropical moisture from remnant typhoons. This system will lift from Kodiak Island across the Kenai Peninsula bringing an area of Gale Force Winds (39-54 mph winds) from out of the southeast along the front. As well as delivering copious amounts of rain to the Southcentral coast, especially across the eastern Kenai Peninsula and Western Prince William Sound where 1.5" to 3.5" of rain could fall. In addition to the rain, gusty gap winds out of the southeast will develop across Turnagain Arm, Passage Canal, and the Copper River Basin.

There is still some uncertainty in the timing of this feature and where all of the storms will meet up which would affect winds across the Anchorage Bowl and precipitation amounts. Stay tuned for changes and details.

Partly cloudy to mostly cloudy in Anchorage Tuesday while we warm up to 61 degrees with scattered showers. Mostly cloudy tonight as we drop down to 50 degrees.

Partly sunny on Wednesday with while we see a high of 62 degrees as well as winds out of the southeast from 10-20 mph along Turnagain Arm as well as in higher elevations. Wednesday night while under mostly cloudy skies we cool down to 49 degrees with winds out of the southeast at 15 mph but up to 30 mph along Turnagain Arm and in higher elevations.

Looking ahead, Anchorage will be cloudy on Thursday with a high of 60 degrees.

Fire Weather: The Copper River Basin remains the focus of any fire weather concerns. High temperatures out there will continue to hover in the mid-'60s with afternoon relative humidity values between 40 percent and 50 percent. Isolated showers and a general increase in clouds are possible late Tuesday as a weakening low-pressure trough moves through the region. Gusty gap winds out of the southeast will increase late Wednesday into Thursday as a strong front enters the northern Gulf. Given the progression of troughs moving through the region, the larger weather scale pattern is transitioning to a more fall-like pattern with cooler and wetter conditions.
