Discussion

In the wake of a cold frontal passage, today will turn out to be mainly sunny, dry, and mild, but the unsettled weather pattern will bring us another shower threat on Wednesday and there can be a PM thunderstorm as well. The upper-level trough of low pressure that will generate our unsettled weather conditions at mid-week will hang around until the end of the week, but important changes will then take place this weekend. Upper-level ridging of high pressure that has been stuck over the western states in recent days will move eastward and reach the northeastern part of the nation by later in the weekend. In fact, this high pressure system will intensify markedly early next week and this can result in 90+ degree afternoon highs in the Sunday, Monday, Tuesday time period across some portions of the I-95 corridor. The big-time warm up is likely to be a 3-day affair and temperatures should return to more seasonal levels during the middle of next week.
