Sunny day, chasin' the clouds away
Now this is pretty darm near perfect. Canadian high pressure is parked over the Great Lakes, putting us in a nice northerly or northeasterly flow of cool, dry air. Sunshine, low humidity and pleasant temperatures right through to the weekend.
We may see a few fair-weather clouds around as humidities slowly rise. And a coastal low could throw some clouds back our way, and maybe an overnight shower this weekend.
But all-in-all, it's relatively cool and dry right into the middle of next week, with highs no higher than the low 80s. Sweet.
Best of all, we can open the windows (well, not here at Calvert & Centre), and let the breeze sweep through.
Blankets and silent air conditioners are the rule all night long, with lows in the 50s, maybe even 40s and upper 30s in the far western counties.
Tropical Storm Erika, meanwhile, appears to have weakened some overnight, as expected. The storm is pretty badly organized for now, and is forecast to weaken further in high-level wind shear as it moves toward the Bahamas. Computer models apparently disagree over whether this storm will survive. The National Hurricane Center thinks not. Here's a snippet from this morning's NHC discussion:
"DESPITE ALL THIS
SHEAR...ALL RELIABLE GUIDANCE RESTRENGTHENS THIS SYSTEM TO NEAR
HURRICANE STRENGTH IN A FEW DAYS. THIS REINTENSIFICATION
DOES NOT SEEM VERY LIKELY AND THE NHC FORECAST IS MUCH LOWER THAN
THE GUIDANCE. GIVEN THE POSSIBLE SHEAR DURING THE FORECAST
PERIOD...IT WOULD NOT BE SURPRISING IF ERIKA DISSIPATED."
Erika is a minimal tropical storm now, with top sustained winds of 40 mph. It is approaching the Leeward Islands, with tropical storm warnings posted for ANTIGUA, BARBUDA, MONTSERRAT, ST. KITTS, NEVIS, ANGUILLA, ST. MAARTEN, SABA and ST. EUSTATIUS, in case you're headed down there.
