The week ahead: Slow moving front syndrome
Jason Samenow @ 12:11 AM
After a powerful line of storms ripped through the area yesterday evening, the responsible front inches closer today, again bringing the threat of storms. Behind this front, another slow moving front will approach, keeping afternoon and evening thunderstorms in the forecast through at least Wednesday before a nice respite late in the week into the weekend.
Today
Afternoon showers and t'storms? Front #1 will likely trigger scattered showers and thunderstorms (40% probability), especially during the afternoon. Most of the day, though, will be partly sunny, warm and humid, with a high in the upper 80s. Overnight, expect partly cloudy skies with lows in the upper 60s in the suburbs and low 70s downtown.
July 4
Late day storm threat. During the day, expect warm and muggy conditions under partly sunny skies. High temperatures should be near 90. By evening front #2 approaches, increasing the chance of thunderstorms (50%), a few of which could be heavy. Overnight lows should be in the low 70s.

Wednesday
T'storm threat continues. Front #2 is likely to slowly pass through the region, keeping thunderstorms in the forecast (60% probability), especially in the afternoon and evening. In the vicinity of the front, mostly cloudy skies should hold high temperatures in the low 80s, but it will be humid. Some of Wednesday's storms could be strong and/or heavy rain producers. We'll have to keep an eye on the flood potential. Late Wednesday night, gradual clearing may begin and low temperatures should range from the upper 60s to around 70.
Thursday
Clearing? Assuming front #2 does not get hung up over us, high pressure should build in Thursday, allowing for increasing sunshine and decreasing humidity. High temperatures look to be in the low to mid 80s. Overnight lows should be pleasant, as temperature fall into the low to mid 60s under clear skies.
Friday
Potentially delightful. As high pressure continues building in from the northwest, the air will be dry and a bit cooler than average. Expect highs in the mid 80s. Look for overnight lows of 60-65.
The weekend
Gradual warm-up, dry. High pressure may well be centered over the region on Saturday, allowing for mostly sunny skies and seasonable high temperatures in the mid to upper 80s. On Sunday, it may warm-up a bit. As the high moves offshore and winds become southerly, temperatures could climb to around 90 with a touch of humidity in the air.
Climatology
The average high this week is in the upper 80s, with the average low in the upper 60s.
