Western & Central Mass Weather Outlook For The Month Of July

Unfortunately, current data points to the potential for the current wet weather pattern to persist through the month of July. The average upper level weather pattern across the United States during the month of July looks to consist of a big high pressure system over the Rocky Mountains into the southwestern United States and upper level trough of low pressure over the eastern and in particular the northeastern United States. This looks to translate to a surface weather pattern of fairly frequent frontal systems moving through on average every 3 to 4 days or so. So while there will be sunshine, there will also be fairly frequent bouts of showers and thunderstorms during July. Temperature: I’m forecasting temperatures that should be about average for a typical July. This means plenty of 80-plus degree days and nighttime low temperatures between 55 and 65 Degrees. While a 90-plus Degree day or two or three is likely during July, I think this July will not even be close to being as hot as last July. If we’re going to have any extended hot weather, it would be near the end of July. Rainfall: I’m forecasting above average rainfall for the month of July. In terms of amounts, my thinking is for rain totals in the neighborhood of between 5 and 7 inches across the region. This is about 2 inches above average. In the next couple of weeks or so, I am watching two time periods for heavy rain - The first is this coming Sunday night into Monday when widespread heavy showers could deposit 1 to 2 inches of rainfall across the entire area. The second time period that I’m watching is the period between July 8 and July 10 when another round of heavy rain that could put down 1 to 3 inches of rain across the area.
