Seattle got almost nothing, while the western slopes of the Cascades and Olympics enjoyed .3 to 1.5 inches. Finally two plots of CG flash density (from weather.bell and Vaisala) above is for 6-hours ending at 5:00 am, while below is 24-hours ending at 5:00 am. As such, I recommend you bring sunglasses, sun block, a brimmed hat, a lightweight long-sleeved shirt and an extra bottle of water or two. According to a study in the journal Microbiome, pregnant women encountered a bacterial exchange, and their children would turn out to have two bacteria called Oscillospira and Ruminococcus, which lower the risk of allergies. Ensemble systems typically tend to be weaker than their operational counterparts (as observed with the ECMWF-Ensemble and ECMWF graphics above), since the ensembles take into account double-digit forecasts and average them all out. Dirt, mud, and other debris can also lower the quality of the water, so change it out quite often. If we study the current pattern of the jet stream you can see we have a trough or a vortex sitting over southeast Canada. In this graphic, valid on December 16th, we see a pair of very strong storm systems, one on each side of Japan.

The temperature during the winter months, which start in December and end in March, remains at an average of 70 degrees. Temperature Refers to how hot or cold an object or place is. And cold air may come back this weekend, with the possibility of lowland snow west of the Cascade crest! And to get significant lowland snow over western Washington, the requirements are exacting and relatively rare. Some mountain locations will get 5-10 inches of RAIN before the next few days are up and several rivers draining into Puget Sound will hit flood stage. Steven Pass, hit by some convergence zone precipitation, has 24 inches and is just short of opening. Over the next 24-h, heavy precipitation will hit Washington, with as much as 2-7 inches in the central and southern Cascades. In stage 3, the atmospheric river strengthens, as does the precipitation (here are the total for the 24 h ending 4 PM Thursday. And the National Weather Service River Forecast Center is predicting flooding on several major rivers draining into Puget Sound, like Snoqualmie, Snohomish, Stillaguamish, Nooksack, and Cowlitz. The National Weather Service is in a strange place with computer power.

The perfect destination in Argentina, Buenos Aires is a city rich in culture, history, and attractions that also boasts spectacular weather. Rain boots come in so many different styles, so you will be able to find the perfect ones for you! But if you live near ones of the above rivers, please take precautions. The morning sounding data from campus (above skewT plot from SPC) indicated saturated conditions above 700 mb, with strong east winds through the troposphere. Above is WRF-GFS radar forecast (from 06 UTC on the 11th) valid at 4:00 MST this early morning. Below is composite radar from 4:00 am this morning – reasonably good forecast that was just a bit under-done in coverage and a little fast in our area. But we can expand on this quite a bit more. He text me and said, you have got to log in your e-mail now and the look at what I have sent you can. You can submit it on this website. Add the entire 72h together over the region and here is what you get: 5-10 inches over the north Cascades, Vancouver Island, and the extension of the Cascades into BC.

The precipitation for the next 24h (ending 4 PM on Wednesday) shows the rain hitting the north Cascades and Vancouver Island fairly hard, with 1-3 inches and a substantial rainshadow northeast of the Olympics. Today (Monday) was a day of profound rainshadowing with westerly flow approaching our region, with the precipitation associated with a warm front. Perhaps a few sprinkles late in the day. A few dollars goes to the UW Chapter of the American Meteorological Society for each calender. Friday will be cloudy with a few light showers. TEMPERATURES WILL BE CHILLY AT LEAST GOING INTO THE WEEKEND. This is not going to be megaflood event like the November 2006 or the January 2009 events. This has certainly been an active storm event for the Southwest, especially for May. The East Asian correlation and the Bering Sea Rule aren’t the only things rooting for this storm- the Lezak Recurring Cycle is also in on this storm potential. This does have an impact on the expected storm in the US. Have an Android smartphone with a pressure sensor (such as Samsung Galaxy III or Galaxy IV)?
