A month from now I think we’ll be cooking in a big way. This is another heavy backloaded season imo. Hard to beat the stability and SAL issues that have been persistent across the tropical Atlantic this decade.

0.01 overnight.

To add to my post from yesterday: “That is a big part of the reason why I question 2013-14 as a “good analog”. This year has a much better chance of seeing a La Niña in the fall/early winter than 13-14 ever did, 13-14 did not have a -IOD event as we do now, it did not have a strong -PDO; in fact it was a Victoria mode PDO which is a pseudo +PDO setup and was only very weakly negative, it was not -PMM and it was a strongly positive QBO all winter, see my monthly QBO numbers above AND it did not have record low arctic sea ice. The only resemblance to this year that I see is the Atlantic tropical season (**so far**) and the big cold pool south of Greenland and up Davis Straight, other than that, big meh as an analog IMO…..” Saw on twitter this morning a couple of folks using 13-14 as their analog, which is fine, everyone is certainly entitled to their opinion and I understand their arguments. However, one person in particular (a met) was completely unaware that 13-14 was +QBO and was incorrectly arguing that it was -QBO. If you are going to make an argument for a certain analog at least do your homework and get all your ducks in a row and facts straight. Just more of a reason to take wxtwitter with a huge grain of salt….even some mets there…..

Move to Naples FL-earliest sunset is 5:40pm

A fave memory was the day after and being sent to see if a dam we had on the Occoquan was still stable. That thing didn’t budge one inch.

Dude. I’ve got a 23 yr old, a freshman in college and senior in HS. The last two were in diapers when I started reading weather boards. And now I’m

We obviously still have a good deal of surplus rain from July into the first week in August in Greensboro. However, with about a third of an inch of rain since the 9th, and entering what appears to be a stable period of dry weather and low dewpoints, we may get some minor drought conditions. No big deal, but it's just crazy how we get stuck in these persistent patterns this year.

That's pretty wild the GFS has nothing in its run...obviously some waves here and there but the overall background is not not conducive for anything outside of some brief development. Have to see if things begin to change more quickly as we near peak.

Homegrown storms will be common soon

7th grader here, she turns 13 in December and I feel older every day

Weenie tap from TOL to S Wey

That 60-day dark green Weymouth pixel. Is that 6” event you had within the last 60 days? It all blends together but I believe so, right?

Keep the dry weather coming!! Last fall was awesome, we didn't miss 1 week of soccer... Droughts here are very temporary, once the bubble pops it goes back to rain every other day in the fall

Wasn't expecting dew near 70

Today will be the first above normal day since 8/17, and then have a stretch of 6 more below 8/26 - .

ACE is now at 37.14 with just a little more to be added from Fernand. This puts 2024 13th highest of the last 75 (83 percentile). The 1951-2024 avg through today is only 22. However, Invest 90L headed to the W Caribbean is now considered dead. Overall, the models including Euro Weeklies continue to look quite a bit quieter than climo through the 1st half of Sept. If that verifies, we’d quickly fall back down to at least NN ACE. From that point on, it would still remain to be seen whether or not PhiEaglesfan will be right about Erin being about the only big deal this season. I’ll be more than happy to give him kudos if he were to be right. But there’s still such a long way to go, especially in a cold ENSO season, which are often backended. In addition, recent seasons have been getting more backended, quite possibly related to GW.

(Ref. NOAA Boston Weather Events) (Ref. AccWeather Weather History) 1814 - In the early afternoon, a strong tornado struck northwest Washington D.C. and downtown. The severe tornadic storm arrived the day after the British Troops had set fire to the Capitol, the White House, and other public buildings. The storm's rains would douse those flames. The tornado did major structural damage to the residential section of the city. The tornado's flying debris killed more British soldiers than by the guns of the American resistance. The storm blew off roofs and carried them high up into the air, knocked down chimneys and fences and damaged numerous homes. Some homes were destroyed. It lifted two pieces of cannon and deposited them several yards away. At least 30 Americans were killed or injured in the heavily damaged buildings, and an unknown number of British killed and wounded. 1885 - A severe hurricane struck South Carolina causing 1.3 million dollars damage at Charleston.

At the time, the center of Hurricane Laura was continuing toward the west-northwest and was located approximately 145 miles to the northwest of the western tip of Cuba. Throughout the remainder of Tuesday Laura continued to strengthen slightly while traveling to the west-northwest across the waters of the central Gulf of Mexico. During the predawn hours, Hurricane Laura strengthened to a category two hurricane as it began to curve to take a track toward the northwest and then to a major category 3 hurricane as winds reached 115 mph as the hurricane's center was slightly less 300 miles to the south of the Louisiana Gulf Coast. Thus, Laura became the first major hurricane of the 2020 Atlantic hurricane season.

Dead. Will be for foreseeable. Embrace it.

We welcome September with open arms.

Q: How about ignoring the human aspect? Which one carried more total heat? A temp of 92F, and dewpoint of 75F, or a temp. of 104F, and dewpoint of 50F? To determine which condition carries more total heat, ignoring the human aspect, we need to evaluate the total energy content of the air, which depends on both temperature and moisture content. The enthalpy of the air, which measures the total heat (sensible heat from temperature plus latent heat from moisture), is the appropriate metric. Wet bulb temperature can help approximate this, but we’ll calculate enthalpy directly using the given temperatures and dewpoints.Given Conditions: Condition 1: Dry bulb temperature = 92°F, Dewpoint = 75°F Condition 2: Dry bulb temperature = 104°F, Dewpoint = 50°F Step 1: Understand the Components Dry bulb temperature reflects the sensible heat (energy associated with temperature). Dewpoint indicates the moisture content, which relates to latent heat (energy tied to water vapor). Higher dewpoint means more moisture, contributing to latent heat, while higher dry bulb temperature increases sensible heat. Enthalpy (in Btu/lb of dry air) combines both sensible and latent heat and is commonly used in psychrometrics to compare total heat content. Step 2: Approximate Enthalpy CalculationEnthalpy of moist air can be calculated using the formula: h=0.24⋅T+W⋅(1061+0.444⋅T)h = 0.24 \cdot T + W \cdot (1061 + 0.444 \cdot T)h = 0.24 \cdot T + W \cdot (1061 + 0.444 \cdot T) where: ( h ) is enthalpy (Btu/lb of dry air), ( T ) is dry bulb temperature (°F), ( W ) is the humidity ratio (lb of water vapor per lb of dry air), 0.24 is the specific heat of dry air (Btu/lb·°F), 1061 is the latent heat of vaporization of water (Btu/lb at 0°F), 0.444 is the specific heat of water vapor (Btu/lb·°F). The humidity ratio ( W ) depends on the dewpoint, which determines the vapor pressure of water in the air. We can estimate ( W ) using the saturation pressure at the dewpoint and the atmospheric pressure (assumed standard at 14.696 psia or 101.325 kPa).Step 2a: Calculate Humidity RatioThe humidity ratio is given by: W=0.62198⋅PvP−PvW = \frac{0.62198 \cdot P_v}{P - P_v}W = \frac{0.62198 \cdot P_v}{P - P_v} where: PvP_vP_v is the vapor pressure at the dewpoint (psia), ( P ) is atmospheric pressure (14.696 psia). The vapor pressure PvP_vP_v can be approximated using the Antoine equation or simplified correlations for saturation pressure at the dewpoint temperature. A common approximation for saturation pressure (in psia) over liquid water is: Pv=exp⁡(20.386−5132Td+459.67)P_v = \exp\left(20.386 - \frac{5132}{T_d + 459.67}\right)P_v = \exp\left(20.386 - \frac{5132}{T_d + 459.67}\right) where TdT_dT_d is the dewpoint in °F, and Td+459.67T_d + 459.67T_d + 459.67 converts to °R (Rankine).Condition 1: Dewpoint = 75°F Td=75°FT_d = 75°FT_d = 75°F , so Td+459.67=534.67°RT_d + 459.67 = 534.67°RT_d + 459.67 = 534.67°R .

Total enthalpy: h=22.08+23.47=45.55 Btu/lbh = 22.08 + 23.47 = 45.55 \, \text{Btu/lb}h = 22.08 + 23.47 = 45.55 \, \text{Btu/lb} . Condition 2: 104°F, Dewpoint 50°F T=104°FT = 104°FT = 104°F , W=0.0130W = 0.0130W = 0.0130 .

Latent heat term: W⋅(1061+0.444⋅104)=0.0130⋅(1061+46.176)≈0.0130⋅1107.176≈14.39 Btu/lbW \cdot (1061 + 0.444 \cdot 104) = 0.0130 \cdot (1061 + 46.176) \approx 0.0130 \cdot 1107.176 \approx 14.39 \, \text{Btu/lb}W \cdot (1061 + 0.444 \cdot 104) = 0.0130 \cdot (1061 + 46.176) \approx 0.0130 \cdot 1107.176 \approx 14.39 \, \text{Btu/lb} . Total enthalpy: h=24.96+14.39=39.35 Btu/lbh = 24.96 + 14.39 = 39.35 \, \text{Btu/lb}h = 24.96 + 14.39 = 39.35 \, \text{Btu/lb} . Step 3: Compare Total Heat Condition 1: 92°F, dewpoint 75°F → Enthalpy ≈ 45.55 Btu/lb. Condition 2: 104°F, dewpoint 50°F → Enthalpy ≈ 39.35 Btu/lb. ConclusionThe air at 92°F with a dewpoint of 75°F carries more total heat (enthalpy = 45.55 Btu/lb) than the air at 104°F with a dewpoint of 50°F (enthalpy = 39.35 Btu/lb). The higher moisture content (higher dewpoint) in Condition 1 contributes significantly to its latent heat, outweighing the higher sensible heat from the higher temperature in Condition 2.Thus, 92°F with a dewpoint of 75°F has more total heat.
