After a warm and humid Father's Day along the I-95 corridor, the weather pattern isn't going to change much as we go through the first full week of summer. Temperatures are anticipated to be above normal while overall precipitation is expected to be below normal this week. Before we get onto the forecast, let's take a look at average temperatures for early summer.
| Average High | Average Low | |
| Boston | 79 | 62 |
| Hartford | 82 | 60 |
| New York City | 82 | 66 |
| Philadelphia | 85 | 67 |
| Baltimore | 86 | 65 |
| Washington, DC | 87 | 69 |
The first half of the week will offer plenty of humidity, but we should get a brief break by Thursday and Friday. Before that break however, we are going to have to deal with uncomfortable heat index values Tuesday and Wednesday.

As for rain chances this week, most of what falls will be isolated to scattered showers and storms that develop during the afternoon. There are two timeframes that will be a bit more interesting than others. The first will be a line of storms that will push towards eastern Pennsylvania late Tuesday afternoon. However, after likely peaking over central PA, this line is forecast to weaken as it continues to push east. The second chance for some organized showers and storms will be Wednesday afternoon as a cold front sweeps towards the East Coast. Again, it doesn't look like there will be widespread rainfall this week, but some will definitely see more than others. Here is a look at forecast total rainfall through Friday evening.

And just a reminder, this is the type of heat that can cause health concerns. Make sure you stay hydrated if you are outside for a long period of time and of course, check on the elderly too. Also, make sure pets have plenty of water available and don't walk them on the hot asphalt during the afternoon.
