The cool pattern in the jet stream that’s dominated much of the East so far this month shows no signs of abating this week. Anchored by a trough aloft, summer-like air will continue to be shunted well to our south. This same pattern has also pushed frequent frontal passages along and through the region, with several shots of rain. There are signs it will be breaking into the upcoming Memorial Day weekend.
The NOAA climate report for April (cited in Andrew’s recent post) revealed a cooler-than normal month overall, and it looks like the trend has continued through at least mid-May. Record heat in California has made national weather headlines in recent days, but it is more than counter-balanced by the anomalously cool temps east of the Rockies. So it goes with the weather.
