A perfect May Day dawned over the Inland Northwest this morning as the region gets ready for one of the busiest weekends of the spring season.
High pressure across the region this morning is not going to last, however.
While today and Saturday should be fair and warm, a new Pacific low pressure area is forecast to slowly encroach on the region later on Saturday in time for Sunday’s Bloomsday run.
The highs today should reach the mid-60s and then upper 60s with increasing clouds on Saturday.
By Saturday evening, the low will have sent enough moisture into Eastern Washington and North Idaho to trigger rain and showers overnight.
National Weather Service forecasters said they expect a dry period early Sunday that may well coincide with the 33rd running of Bloomsday in Spokane.
Dawn on Sunday should bring temperatures in the middle 40s but warming to near 50 by the 9 a.m. race time in Spokane.
A Weather Service forecast table shows the conditions at 9 a.m. should be 49 degrees with a 50 percent chance of showers under south wind at 7 mph. By 11 a.m., it would warm to 53.
