Unsettled weather starts the week and it may finish it if Hurricane Isaac's leftover rains impact us.
Some school districts are back in swing this week as summer winds down. The good news is an extended weekend is ahead of us. The bad news is that it may rain for part of it as the leftovers from Hurricane Isaac possibly track into the Mid Atlantic. Isaac's remnants won't produce Irene or even Lee-like impacts across the region. No winds to 80 miles per hour. No rainfall that's measured by the foot. Nor will there be coastal flooding issues to deal with or orders to get the hell off the beach. Those type of impacts will be felt along the Gulf Coast, where Isaac will make landfall on Tuesday evening. Isaac's future from landfall is less clear at this point, with some computer modeling suggesting it will track through the Ohio Valley and …

The week's weather starts on a damp note but should generally be nice and not too hot.
We've had a rainy run the past couple of weeks– Philadelphia has picked up over four inches of rain since Aug. 1, with Reading and Allentown both pcking up over three inches of rain. Outside of a wet start to Monday, most of the week ahead should feature rather nice weather. Monday's rainy start is associated with a disturbance that is riding along the cool front that pushed through the region on Friday night and Saturday. Once this gets out of the way later in the morning hours, Monday afternoon should wind up nice. The other potential chance of rain in the work week is on Wednesday, with a weak trough that will pass through the region and up the coast. It could trigger a few passing showers as it moves through. Outside of Wednesday, the …

The Montgomery County Department of Safety's live incident feed was alight with reports of road obstructions, disabled vehicles and even a water rescue.
While repeated thunderstorm warnings recently have gone unrealized in Norristown, heavy rains did come Friday morning and caused a myriad of problems for residents, commuters and emergency responders in the municipality. Reports of flooding, road obstructions and disabled vehicles kept emergency responders and Public Works crews busy most of the morning. Readers also report the DeKalb Street Bridge was shut down briefly this morning due to flooding on the Norristown side, but was reopened shortly ofter 10 a.m. The Norristown Fire Department was dispatched for two water rescues involving vehicles caught in flood waters at DeKalb and East Washington streets and Arch and Chestnut streets – low-laying areas that flood quickly when heavy rains…

Chances of thunderstorms and a few 90-plus degree days are in store.
So far this year, rainfall deficits in our region run between five and nine inches, which generally means that we've seen about two-thirds of what is considered "normal" rainfall. While we don't need or want a repeat of last August and September around here, lawns and gardens wouldn't mind a bit more rainfall. Last week's bouts of rain definitely helped. More is on the way this week. Thunderstorm chances are in the forecast for late Monday and again on Tuesday as a frontal boundary out to our west crosses the region over those two days. Thunderstorms will be scattered so not everyone will see rainfall; however, because of increased instability in the atmosphere we'll see the potential for some strong or severe storms in parts of the region…

There's a potential for heavy rain and thunderstorms Tuesday through Thursday.
This weekend's foray into summer temperatures and warmth is thankfully not the start of a prolonged heat wave. The combination of a weak backdoor cool front pushing down from New England and a weakening ridge of high pressure in the atmosphere will help nudge temperatures back closer to reality for the start of the week. As the ridge of high pressure continues to weaken, a cool front to our west will nudge east towards us for the middle portions of the week, bringing us a potentially heavy rain and thunderstorm event for Tuesday night and Wednesday. Computer projections range anywhere from an inch of rain to perhaps over three inches for the Tuesday night and Wednesday time frame, with higher rainfall totals possible over the Poconos. …

Low humidity and mild temperatures mean this week will feel more like early fall than late spring.
Personally, I like late spring and early summer quite a bit ― it's not my favorite weather when compared to October, but this time of the year brings you some of the longest days of the year. If the pattern is right, you can get some really nice weather that rivals early fall – low humidity and milder temperatures that we'll miss when summer heat arrives in a few weeks. Despite chance of showers, this week will at least provide the combination of lower humidity and temperatures that are more typical for early May than early June. The cause is last Friday's storm system that brought rain and wind to the region. The storm system's energy in the upper portions of the atmosphere ended up parking itself over the Great Lakes this past weekend …

Temperatures are on the rise this week, but so is the chance of more thunderstorms.
Amazingly, despite what will likely be the warmest spring on record in the Delaware Valley, we have yet to hit 90 degrees. The potential for the season's first 90 degree day looms large over the next couple of days, and today's Memorial Day holiday might be our best shot in this upcoming summery stretch. Despite a chance in the forecast for some pop-up thunderstorms, most of us should dodge any storm development in the afternoon hours on Monday. In place of rain and thunder will be heat and humidity in what may be our hottest day of the year so far. The heat won't last for too long. A cool front in the Great Lakes states will slowly work east and cross the region on Tuesday night and into Wednesday. Cooler weather will gradually ooze in …

Tom "Thunderstorm" Thunstrom takes a look at a slow moving system.
Last week's article talked about the potential for a coastal low to develop and wreak havoc on our weather this week. That potential has been realized as a coastal trough is aligned off of the Carolina coast and will slowly push northward into our area for the start of the new week. The good news? It won't rain all of the time. The bad news? It might take until Memorial Day Weekend for it to clear out of here. This slow movement isn't unusual for May systems that develop and like to linger off of the Atlantic coastline. As the Bermuda high and the Southeastern US "heat high" develop, frontal boundaries tend to stall out along the East Coast, sometimes hanging out for a period of days before they finally get pushed out to sea or simply …

Flood warning issued until 2:30 a.m. in Montgomery County.
Tuesday, May 15, 2012
The National Weather Service has issued a Flood warning for Montgomery County until 2:30 a.m. A series of severe thunderstorms are currently moving across our region producing rainfall amounts upwards of two inches an hour. The heavy rainfall will cause urban and small stream flooding. A flood warning means that flooding is imminent or has been reported. Stream rises will be slow and flash flooding is not expected. It's harder to recognize the dangers of flooding at night, so be especially cautious. Do not underestimate the power of flood waters, even a few inches of rapidly flowing water can carry away your vehicle.

Rain in the earlier part of the week will give way to sunshine by the weekend.
May is one of those months that can bring us both summer-like heat and cool mornings. Sometimes frontal boundaries like to hang out over the region in may as they lose their punch and run into the developing summertime Bermuda high in the Atlantic. We've had a few "slow moving fronts" through the region in the past three weeks. This week promises yet another front and another slow track through the region between Monday and Wednesday. It won't rain all day on Monday or Tuesday, but when it does, expect a heavy downpour. Some spots could pick up a couple of inches of rain in the next couple of days. The best chances for heavier rain will be from Monday night into Tuesday morning. The main rain axis then shifts into New Jersey for the …
