Temperatures on Friday through the weekend will warm to the highest values of the season so far, with high temperatures reaching the 80s for much of the region. && .DISCUSSION... Tonight and Wednesday: The Low from the past few days is east of the Inland Northwest. It is still bringing some isolated shower activity to extreme Eastern Washington and the Idaho Panhandle through the evening. As the low slides farther east, it will push a weak band of showers north to south over these areas. Shower activity will diminish over these areas through Wednesday morning. The morning lows will be coldest for the next several days as a warming, dry trend will begin to build into the region. The lows will be in the 30s to low 40s. The highs will be in the upper 50s to low 70s. Thursday through Sunday: The period will be dominated by a ridge off the coast. The ensembles are in good agreement of dry, warming trend through the weekend. Each day will be a few degrees warmer than the previous before peaking over the weekend. Temperatures are expected to average 10-15 warmer than normal by the weekend. The region can expect widespread 80 temperatures by the weekend. The Central Basin could see some locations reach into the low 90s. Overnight lows will be in the upper 40s and 50s. Monday and Tuesday: The ridge pattern begins to flatten late Sunday breaking the warming trend from the weekend. The ensembles are not showing much in the way of precip. There are a couple of weak shortwaves that slide through Southern BC. These could produce light shower activity along the border. Temperatures will trend to season normals for this time of year. Highs will be in the upper 60s to 70s. Lows will be in the 40s to low 50s. /JDC && .AVIATION... 06Z TAFS: Winds will continue to gradually decrease into Wednesday as low pressure continues to pull away from the area and high pressure noses in.
