#Hermiston #weather 20260527 Partly cloudy and warmer today with highs around 28ºC. The spice comes tomorrow as a low pressure system spins warm, moist air into the region from the south. Look for Thursday highs around 32ºC with possible t-storms in the afternoon. The SPC has a marginal (level 1/5) risk of severe t-storms for the Columbia Basin and nearby areas with the primary threat being severe wind over 93 km/h. Showers taper off Friday morning with clearing skies and strong winds. Highs much cooler, closer to 23ºC. Sunny but mild through the weekend. @ORwx
