We have been very lucky this spring! Our severe weather reports have been minimal due to the northern position of the jetstream, which in turn would typically allow for some hot temperatures; however, we’ve been fortunate that little cut-of low disturbances have kept our temperatures from soaring out of control, and most importantly, they have provided us with ample chances for rain.
This same story is unfolding over the first week of summer. Look at the position of the jetstream in the picture above. A major ridge has parts of the West sizzling under 850 mb temperatures approaching 30 degree Celsius. If this was the case for us, we would easily be experiencing temperatures in the mid to upper 90s, but that’s not the case.
Look at the upper level winds in this second picture. I have drawn in an upper level cut off low around 18,000 ft. This low will provide us with clouds and chances for rain over the next couple of days, and it’s what I call natural air conditioning. Look for seasonable highs climbing into the mid to upper 80s to near 90 degrees.
