Possibly a chance for the higher elevations in Anchorage (as in where people live, not the peaks) has a chance to see some snow on Thursday morning.

patrick7032 Posted September 28, 2011 Author Share Posted September 28, 2011 The pattern is looking to amplify as we head into the upcoming week. A strong jet develops which looks like it could dive into the Pacific Northwest in a week to 10 days. Link to comment Share on other sites More sharing options...

patrick7032 Posted September 30, 2011 Author Share Posted September 30, 2011 It's getting closer to that time of year.....here is an exert from this morning's discussion from the Anchorage Forecast Office which verified in lower elevations as well in southwest Alaska at Dillingham. .SHORT TERM FORECAST... .SOUTHCENTRAL ALASKA... SHOWERS/RAIN AND SOME MIX OF SNOW(HIGHER ELEVATIONS) WILL SPREAD ACROSS SOUTHCENTRAL TONIGHT AS THE UPPER TROUGH MOVES EAST. PATCHY FOG AND STRATUS WITH SUBSIDENCE ON THE BACKSIDE OF TROUGH MAY FORM OVER COOK INLET LATE TONIGHT/EARLY FRI. FRONT MOVING IN FROM THE EAST AND SOUTH WILL BRING RAIN TO COASTS FRI AND SAT...WITH SOME SHOWERS INLAND. EXPECT THAT THE STRONG WINDS OVER THE GULF FRI MORNING WILL SPREAD TO THE NORTH GULF FRI EVENING AND CONTINUE INTO SAT.

MTBLANC Posted September 30, 2011 Share Posted September 30, 2011 Glad you enjoyed the pic and that my college in Anchorage was able to capture such a beautiful pic. There were some northern lights the past night here; I unfortunately was not able to take a correct shot ! Yesterday -3.0/10.4, today 2.2/8.2. It is milder here in south Yukon with the south-east wind. Tomorrow, some snowflakes or raindrops before a sunny and cooler weekend. Have a great evening !

MTBLANC Posted September 30, 2011 Share Posted September 30, 2011 1.3C this morning, with some light rain (snow?). 1.4 mm. If you want to see some snow (I am not sure, but think there will be), just have a look at the webcams in the territory http://meteowhitehorse.ca/wxwebcam.php. It is still dark, but should be fine in one hour ! Link to comment Share on other sites More sharing options...
NIUmetGF Posted September 30, 2011 Share Posted September 30, 2011 Lots of freshies on the front range this morning, doesn't show up great in the webcam pic. Maybe later in the day. Freezing level down to 2300ft. 1.3C this morning, with some light rain (snow?). 1.4 mm.

patrick7032 Posted September 30, 2011 Author Share Posted September 30, 2011 ALASKA VOLCANO OBSERVATORY WEEKLY UPDATE Friday, September 30, 2011 11:00 AM (Friday, September 30, 2011 19:00 UTC) CLEVELAND VOLCANO (CAVW #1101-24-) 52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m) Current Volcano Alert Level: WATCH Current Aviation Color Code: ORANGE The eruption of a lava dome in the summit crater of Cleveland Volcano continues. Satellite observations over the past week detected elevated surface temperatures at the summit on September 23 and 28 and slow growth in the size of the dome. As of September 26, the lava dome was entirely contained within the summit crater, approximately 15-20 meters (49 to 66 feet) below the eastern rim. AVO has received no other reports of activity at this volcano. If the lava dome continues to grow in the summit crater, the possibility of an explosive event increases. With continued lava dome growth, lava may eventually overflow the crater rim to produce a lava flow and/or collapse to produce pyroclastic flows. Sudden collapse of the effusing lava could result in the generation of a volcanic ash cloud. However, lava may continue to erupt without an explosive event. It is possible that explosions from the summit crater vent could produce ash clouds that may exceed 20,000 ft above sea level. These events can occur without warning and may go undetected in satellite imagery for hours. However, lightning associated with significant ash-producing events may be detected within minutes using an automated alarm system. AVO does not have a real-time seismic network on the volcano and thus we are unable to track local earthquake activity related to volcanic unrest, provide forecasts of eruptive activity, or confirmation of explosive, ash-producing events. In the event of a large explosive eruption like that in 2001, it is possible that seismic signals may be recorded on AVO seismic networks at nearby volcanoes. AVO will continue to monitor the volcano using multiple sources of satellite lightning detection, and distant seismic data. Cleveland volcano forms the western half of Chuginadak Island, a remote and uninhabited island in the east central Aleutians. It is located about 75 km (45 mi.) west of the community of Nikolski, and 1500 km (940 mi.) southwest of Anchorage. The volcano's most recent significant eruption began in February, 2001 and it produced 3 explosive events that produced ash clouds as high as 12 km (39,000 ft) above sea level. The 2001 eruption also produced a rubbly lava flow and hot avalanche that reached the sea. The most recent minor ash emissions were observed in January and June 2009.

patrick7032 Posted October 1, 2011 Author Share Posted October 1, 2011 It looks like a couple of good storms will hit the Alaska Peninsula and Aleutian Island chain next week. Below is an exert from this mornings forecast discussion from the Anchorage Forecast Office and a "sample" marine zone for one of the effected areas. Note the 60kt+ winds in the model data for the middle of the week. The jet pattern certainly supports it. Looks like the jet pattern will stay "active" through the week. We may have a storm with HURRICANE FORCE WINDS by mid week. A sign of things to come in another month when the "real" storms start to "spin up"........ .ALEUTIANS...A POTENT LOW PRESSURE SYSTEM AND ITS LOW LEVEL JET HAVE ALREADY SUPPORTED WIND GUSTS ABOVE 50 MPH AT SHEMYA EARLY THIS MORNING. WHILE THIS LOW WILL MOVE SLOWLY EASTWARD FROM THE KAMCHATKA PENINSULA OVER THE NEXT FEW DAYS...ITS ASSOCIATED FRONTS WILL BRING STRONG GUSTS ACROSS THE BERING BY THIS EVENING. THE MORE POTENT STINGER JET ALONG THE SOUTHERN SIDE OF THE LOW WILL BRING STORM FORCE WINDS TO THE WESTERN ALEUTIANS BY SUNDAY AND CENTRAL ALEUTIANS BY SUNDAY EVENING.

Here are some pictures I took on the Alaska Highway between Whitehorse and the lake of Kluane. Sunny conditions, only 2C at 1000m high. You can see St-Elias Mountains, I love the colors at this season with blond grass, first snow on the peaks, glaciers, ... Some elks: Ciao for now!
