Fxus66 kotx 241129 afdotx area forecast discussion national weather service spokane wa 429 am pdt Sat jun 24 2017 Synopsis Warm and sunny weather will be in place this weekend with widespread 90s expected by Sunday. Monday will also be warm with increasing clouds and chance for showers and thunderstorms late in the day. A return to cooler, more average temperatures are expected by the middle of next week, with breezy conditions possible late Monday through Tuesday. Discussion Tonight through Monday night: a ridge of high pressure continues to amplify along the coast today, shifts into the inland nw Sunday, then slides to the east Monday. Conditions today and tomorrow will be warm and sunny accompanied by light east to northeasterly winds. Afternoon highs climb into the 80s and 90s this afternoon then 90s for Sunday with isolated 100s in the lower basin. Uv indices will be maxed out around 10 or within the very high category. Per the epa index, this means there is a very high risk of harm from unprotected Sun exposure. Taking extra precautions such as finding shade periodically, wearing sunscreen, hats, and sunglasses is highly recommended for those exposed to sun exposure between 10am and 4pm. As the ridge axis slips to the east Sunday night into Monday, we will see an influx of midlevel moisture leading to an increasing risk for showers and thunderstorms. Two shortwaves will also come into play, the deeper of the two will skirt the area from the north with a second coming off the ERN pac off the N ca coast. The air mass will be quite dry with the initial influx of moisture Sunday night into Monday morning so thinking this will mainly equate to ACCAS (altocumulus castellanus) with spotty sprinkles. However as the air mass continues to slowly moisten and upper levels begin to cool, instability will continue to increase Monday afternoon. There remains very low confidence whether surface based convection will be able to fire prior to Monday evening due to the uncertainty of a kicker to overcome a strong cap. If cells are able to form, there is a potential for a few stronger cells capable of hail and gusty winds. If the cap holds, Monday will generally be warm with a mix of clouds and sun. Confidence increases for showers and t-storms Monday evening and night as the shortwave off the ca coast treks inland through n oregon. There is a decent chance that showers and storms develop along this feature and pass over areas of SE wa and nc id. Exactly how far north or south is still uncertain and leaning toward the best chances south of a line from avery to la crosse at this time. The forecast also carries a slight chance for t-storms in the ne mtns. The northern branch shortwave will be passing through

southern bc during this time ushering a cold front into the region. This boundary may be enough to spark a few cells over the northeastern mtns Monday afternoon evening. The cold front presses into central wa Monday afternoon bringing a push of winds in the lee of the cascades and western basin. The combination of warm temperatures, increasing winds, and low humidity will promote several hours of critical fire weather conditions prior to sunset. Monday which looked to be the warmest day of the week will likely fall close to Sunday's readings give or take a few degrees due to some cloudiness. Sb Tuesday through Saturday: any remaining shower or thunderstorm activity will exit the area by Tuesday morning as drier air filters into the region behind the front. The GFS has come into better agreement with the ec keeping the upper level low further north over central ab. The main concern Tuesday will be the breezy to gusty conditions as the cross cascade pressure gradient remains tightened. The combination of dry and breezy conditions following several hot and dry days will increase fire weather concerns, especially for the finer fuels across the basin. Afternoon highs will be about 10 degree cooler Tuesday compared to Monday. As the low upper level trough continues to shift east the inland northwest will sit in a northwest flow regime, becoming more zonal toward the weekend. Models still disagree on the finer details but enough weak waves clip the N idaho panhandle to keep the occasional shower or thunderstorm mention in the forecast over this area. Otherwise look for dry conditions elsewhere with high temperatures in the mid 70s to mid 80s Wednesday, warming into the mid to upper 80s by late week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
