While troughing consolidates over the Upper Midwest, flat high pressure will establish itself over the EPAC. While not fully progressing over the Western US, it will be limited by troughing over the PACNW. A disturbance may brush Mammoth Saturday, but H5 heights should still increase towards the 586 dm range, in a flat quasi-zonal flow regime. In other words, a more typical late April pattern thru the weekend and temps hitting 77° degrees in Bishop and 51° in Mammoth by Sunday. So prepare yourself for a pleasant weekend ahead…DMATT
