DAYS 1-5 (JUNE 15-19)
Unsettled weather will continue today as additional showers form in the area as a result of humid air, an upper level low pressure trough, and a surface cold front moving slowly through the region. While most times it won’t be raining in any given location, any location may see passing showers and downpours, even some thunder remains a possibility too. Once the front gets by the region it will dry out this evening and tonight. High pressure builds in for Wednesday and Thursday but above there will still be a couple upper level disturbances which bring colder air in aloft and help initiate diurnal cloud development. This is expected both of those days, especially Thursday with the coldest pocket of air will be passing by above. Surface high pressure slides offshore Friday when it warms up nicely, and this continues into Saturday but may be interrupted by showers and thunderstorms as a cold front moves into the region from west to east…

DAYS 6-10 (JUNE 20-24)
West-to-east “zonal” flow will be the weather pattern as we reach the summer solstice on June 20 and for the early days of summer 2021. However this flow does carry disturbances in it, and one such with a warm front / cold front combo with low pressure passing to the north will bring some unsettled weather at some point later June 21 into June 22 based on current timing, and another wet weather system may make a run at the region at the end of the period.
DAYS 11-15 (JUNE 25-29)
Overall west-to-east flow pattern is expected to continue but slowly weakening with a northward lifting of the jet stream. This is a warm pattern with limited opportunities for showers and thunderstorms.
