FORECAST IN DETAIL

By David Streit, CWG Meteorologist

The next two days are setting us up for a fall! We will be spoiled with above normal temperatures and none of that nasty humidity that had us ratcheting up the A/C over the weekend. However, a major league cold front will put an end to all the fun bright and early on Saturday. We could be greeted by a few showers or thunderstorms Saturday morning but they will quickly be gone and a very windy day will ensue. The real chill arrives on Sunday and Monday with readings at least 10 degrees below normal.

Today (Thursday): A band of showers passing just to the north of the area could give us a few clouds speeding by early in the morning. However, it's all good from there with highs in the low 80s, about 10 degrees above normal, and low humidity. Winds somewhat breezy around 10-20 mph. Confidence: High

Tonight: This evening is made for patio-dwelling. Temperatures start in the 70s and slip to the 60s later in the evening. The low humidity allows overnight lows to reach the upper 40s suburbs to mid-50s downtown. Winds remain light and skies clear. Confidence: High

Keep reading for the forecast through Monday....

Tomorrow (Friday): Remember yesterday? Here we go again with lots of sun and light breezes. Highs may be just a degree or two cooler but upper 70s to lower 80s makes for a fine end to the work week. Humidity inches up by afternoon but nothing uncomfortable. Confidence: High

Tomorrow Night: There is no worry about a jacket if you go out on the town tonight. Temperatures in the 70s most of the night (but bottoming out in the 60s) and light breezes last through the evening. Humidity and breezes pick up after midnight. Confidence: Medium-High

A LOOK AHEAD

Saturday dawns with a strong cold front bearing down on the city. There is the possibility (50% chance) of a few morning showers or thunderstorms, but skies clear quickly and brisk winds from the southwest shift to howling out of the northwest by mid-morning. Winds of 15 to 25 mph with gusts to near 40 mph are likely with highs in the 70s. Confidence: Medium-High

Mother's Day Sunday is going to be a shock to the system with morning lows in the low-to-mid 40s and highs only reaching the low-to-mid 60s. That is nearly 10 degrees below normal. However, there is some solace for all the moms on their special day; only light breezes and sunny skies throughout the day. Confidence: Medium-High

Monday morning commuters can rely on cool temperatures to wake them up, even in the coffee fails them with readings in the upper 30s to lower 40s. Temperatures should recover much better with highs in the mid-to-upper 60s. Light winds and mostly sunny skies combine to make it pleasant by mid-day. Confidence: Medium-High

Lower you humidity? Hip-hip-hooray! Excited about this "10" day? :)

We are significantly above-normal in temperatures for at least the past two months, and below-normal in rainfall.

My anxiety about drought is setting in...National Airport is fully 3 inches below-normal for the year.

Our neighborhood tree planting with Casey Trees last weekend went well, but surface moisture was dusty-dry.

What are the forecast chances of precipitation over the next month from HPC? Let's hope we get significant rain very soon!

So what about a hike on Old Rag on Saturday? Say, about 11am-4pm? That's west of here, which should clear off earlier than DC, but it might be a tad breezy up there, then? No lightning though?

Ennepe68, it sounds like the chance of t-storms will be minimal by the time you start your hike per the NWS discussion:

SATURDAY MORNING...COLD FRONT CROSSES THE REST OF THE CWA... DOWNSLOPING FLOW AND TIMING OF FROPA IN THE EARLY MORNING SUGGESTS A MAINLY DRY PASSAGE EAST OF THE ALLEGHENY MTNS...SCHC FOR TSTMS. ADDITIONAL TSTMS POSSIBLE AHEAD OF THE FRONT FOR SRN MD AND THE BAY THROUGH MIDDAY.

SATURDAY...EXPECT STRONG WESTERLY FLOW AROUND 20 MPH WITH GUSTS OF 30 TO 35 MPH. WITH DRY AIR SPILLING INTO THE EGION...AND LITTLE PRECIP EXPECTED EAST OF THE ALLEGHENY MTNS THAT MORNING...ENHANCED
FIRE WEATHER CONDITIONS ARE EXPECTED FOR THE AFTERNOON.

Just be careful with fire and don't get blown of any ledges on Old Rag.

Ennepe68, the biggest concern will be the winds, particularly at higher elevations. You will need to be careful with this powerful gusts!

Tom, yes, the dryness is definitely creeping into the picture and we are not too wet over the next few weeks. Right now, our thinking for the summer is closer to seasonal precipitation levels.

The National Weather Service is making no forecast for this area (EC means equal chances of anything happening), but we are on the edge of the wet thinking from Baltimore northward.

I rode my bicycle to work yesterday and it was fairly windy. Not a big deal with temps as nice as they are, but they may have kicked up the tree pollen. My throat was scratchy and inflamed. Today was much more calm. the main culprits yesterday were pine and oak. I'll remain shuttered in my office today and at home tonight. I had hoped to mow the lawn yesterday, but chickened out. I broke down this am and took a chlor trimetron. I have another in my shirt pocket.

Let's keep up the dry weather. We don't need a lot of depressing rain, particularly on my dance nights.

I'd rather have today's weather than a bunch of depressingly raw cloudy weather. We had enough of that last spring.
