A late season snow for western Wyoming Tuesday. Tourists visiting may be surprised when they wake up Tuesday morning. Certainly not unprecedented for the area but compared to the rest of US, visitors may be caught off guard. 1-3″ at Old Faithful, but more expected at the higher elevations.
High temperatures 15-20 degrees above normal in Idaho Wednesday. Temperatures will top out near 100 degrees in the Treasure Valley and Magic Valley. Even mid 90s as far north as Lewiston. Snow at the high elevations is causing some flooding especially on the Boise River. This hot weather will not last much longer as huge cold low pressure will take over later this week into the weekend.
Very chilly temperatures are expected in New England Tuesday with widespread 50s for highs. The cold will be accompanies by showers and gusty winds making for a very raw day for the first week of June. Only 51 degrees expected at Boston which will be about 15 degrees below normal. There will be several more days of chilly weather before high pressure finally builds over the East Coast. Highs reaching up to 80 degrees by this weekend.
High temperature will approach 110 degree today in the deserts of Arizona. This is a bit ahead of schedule for the area and about 6 degrees above normal for Phoenix. No relief from the heat until late next week when it may drop back to 100.
Highs only in the 60s in the northern parts of Colorado with much cooler temperatures in the mountains. Highs only in the 30s across much of Rocky Mountain National Park (see below). These highs are about 10-15 degrees below normal. Better across the southern part of the state where low 70s are expected. Temperatures will slow warm through the weekend and the chance of showers will diminish.
A cool and showery day expected across much of New England. Highs only in the 50s across the state of Massachusetts which will be about 15 degrees below normal for the 3rd week of May. Friday will be very similar but a warming trend will start this weekend going into next week.
A very windy day expected across Big Sky Country today and tonight. Widespread gusts 50-60 mph including Great Falls with local gusts in the mountains over 65 mph. This could cause damage to trees and power lines. The wind will usher in a few showers and cooler temperatures the next few days.
