Monumental Forecasting: September 2010

Forecast for October 1, 2010

Today:
Forecast for today will be much improved from Thursday. Fall air will settle into the region and we'll see the sun again by the afternoon. A few rain showers will remain possible early, but they should taper off shortly after sunrise, if not sooner.

High: 73
Low: 52

Weekend:
The weekend looks like fall, and for one I can't wait. Highs will not reach 70, but we'll still have sunshine with highs reaching comfortable levels in the upper 60s. Starting off next week, will be a similar story. We'll be dry with highs near 70 Monday and Tuesday.

As always my forecast flier is attached below:

Forecast for September 29, 2010

Remnants of soon to be Tropical Storm Nicole will bring heavy rain potential to DC:

Rainfall forecast from soon to be Tropical Storm Nicole

There will be a sharp cutoff, but this is some rain we need, just not all at once. Up to 6 inches of rain could fall in portions of the DC Metro. This is a good time to remind everyone that if you're driving and see a flooded roadway: Turn Around, Don't Drown. The rest of the forecast is below, stay dry everyone!

Today:
Clouds will fill in and rain will begin pelting the area as we head into the evening commute and nighttime hours. Expect highs in the low to mid 70s with lows only dropping back into the mid to upper 60s.

Thursday: Rain showers will continue through the day as Nicole heads to the North. Expect rain to begin tapering off Sunday night. This could potentially alter many travel plans, so make sure to check on any flights you may have on Thursday, especially in AM and afternoon hours.

Weekend:
For the weekend we will be able to dry out. Temperatures will be comfortable with highs feeling like fall. Friday we'll be in the low 70s. Saturday and Sunday highs will only reach the upper 60s!

Forecast for September 27, 2010

Today:
Rain will taper off as we reach the Midday hours. Expect peeks of sun this afternoon as we top out near 80 degrees. This will be the last 80 degree day for a while as a front drags more fall like weather with it into our area. Saturday temperatures aren't even expected to hit 70!

Yesterday:
National reported 0.19" of rain, which means they missed much of the precipitation they needed. Other sites, such as Baltimore, reported up to an inch of much needed rainfall. Luckily we'll have another shot to put a dent in our drought on Wednesday night/Thursday.

As always, the forecast flier is attached for your enjoyment.

Record Setting Summer:
Saturday we topped 90 degrees for the 67th time this summer. This ties 1980 for the most 90 degree days in one year on record, and we still have plenty of time to break it. The good news is that we will not come close to 90 through at least the next 5 days.

Check out the 5 day forecast, and what's going on across the nation with my forecast flier below.

Forecast for September 24, 2010

Today:
Today could be another record hot day across DC. It will certainly be our 65th 90 degree day this summer, and it will approach our record high for this date as well. I'm anticipating that we'll top out in the neighborhood of 95 degrees! The good news is this weekend we are expecting a big cool down.

Tonight:
Quiet weather tonight with mild temperatures continuing. Lows will be in the upper 60s and low 70s.

Weekend:

Another sunny day is in store for the District on Saturday as temperatures climb to the upper 80s on Saturday. For those of you running the Clarendon 5 and 10K's, the weather looks just fine.

Sunday will remain dry as clouds start to build into the region in the afternoon. A front will begin moving through the region late on Monday and bring with it rain chances that will last through the day on Tuesday. Currently it looks like we'd receive 1+" of rain, which is badly needed.

I'll add graphics as I become more accustomed to blogging, but if there is anything you for sure want added let me know!

Forecast for September 23, 2010

Today:
More sunshine and more warm temperatures. We will possibly top out above 90 once again. This would be our 65th day of the year at 90 degrees or warmer and will bring us within two days of tying the record for most 90 degree days in a year, set back in 1980.

Tonight:
Muggy conditions will continue, and it will feel more like July than September in the District.

Longterm:
Friday will be another warm day as a cold front approaches this weekend. Saturday temps drop back to the mid 80s under partly sunny skies. Sunday may include a light shower or two, but otherwise expect gray skies as temperatures stay more seasonable (Mid 70s). Much of the region missed rain again today and unfortunately we need it even more now.

Weather Highlights:
Not everyone missed the strong T'Storms on Wednesday. Leesburg was pounded with penny to nickel size hail and many flights into DCA were delayed to IAD until the storms passed.

Forecast for September 22, 2010

Today
High: 90
Heat and Humidity will move back into the Mid-Atlantic today. Expect sunshine to blanket the region early in the day, with clouds building in during the afternoon and evening hours. Winds today will be out of the SW at 5-15 mph.

Tonight
Low: 70

During the overnight the Washington Metro will have a shot at some scattered showers and thunderstorms. The rain is badly needed, but unfortunately many areas will miss the scattered showers. Winds will stay light out of the S through the night.

Thursday - Saturday
Thursday and Friday will be warm and humid across the region. Highs will be in the 90s ending a summer for the record books. Saturday a stronger front will move through the region. We'll have a shot at some showers as we move into Sunday as temperatures drop to 70 for our highs!

Forecast for September 21, 2010

High Pressure will dominate the weather pattern today, but it will begin sliding to the East and this will aid in the return of southerly winds. While today will be quite comfortable, the heat will begin building back in starting tomorrow. Wednesday and Thursday temperatures will once again be near 90 degrees. We've had over 60 90 degree days this Summer so it is not surprising that she wants to leave a bang. The first official day of Autumn is this Thursday.
