JakkelWx Posted July 18, 2020 Share Posted July 18, 2020 Maybe the fabled thunderstorm of all thunderstorms to end the heatwave monday evening will come. Link to comment Share on other sites More sharing options...
CAPE Posted July 18, 2020 Share Posted July 18, 2020 Sunday looks hot, but dew points should not be too bad. Monday clearly looks like the day that will feature the highest heat index values, with temps in the mid to upper 90s and dew points well into the 70s. HI values of 110 look likely. 1 Link to comment Share on other sites More sharing options...

For my immediate area the Euro has consistently been 5 - 10 degrees too warm for the past week with afternoon highs. The GFS and GEM have been more accurate.

nw baltimore wx Posted July 18, 2020 Share Posted July 18, 2020 I’m getting a Covid haircut under the shade of our big swamp maple and it’s not bad at all outside in the shade. Nice breeze and low’ish dews are making for a nice summer day. Tomorrow and Monday, probably not so much. 1 Link to comment Share on other sites More sharing options...

Baltimorewx Posted July 18, 2020 Share Posted July 18, 2020 Hot day means a slow day at the park but it’s really not unbearable with the relatively low humidity. Not desirable of course but not oppressive. Tomorrow and Monday shall be a different story I suppose but I’ll be inside the AC Link to comment Share on other sites More sharing options...
CAPE Posted July 18, 2020 Share Posted July 18, 2020 91 here. I have been suspecting my DP has been reading a bit high... 70 right now. Not totally out of whack, but most other obs are in the mid 60s currently. Link to comment Share on other sites More sharing options...

Ggem and euro suddenly look way less impressive for rainfall next week. Gfs still pretty wet. That’s never a fair fight.

Yeah I am surrounded by corn fields, and closer in- a bunch of trees. Also, my experience with capacitive based RH sensors is they are subject to drift over time, and tend to read higher until they saturate. I am pretty sure that is the sensor type that is used in most of these stations. I used to replace the RH sensor on our station at work every couple years. My station is pretty new though, so not thinking thats a problem. Link to comment Share on other sites More sharing options...

Doesn't take long to go dry this time of year. Looks like some chances for scattered stuff Tues- Thurs, and maybe something more widespread heading into next weekend, but thats just looking at the GFS. eta- 12km NAM has some convection late Mon into early Tues. Looks like some upper level perturbations moving west to east in the flow aid in initiating it. Looks scattered though. Link to comment Share on other sites More sharing options...
JakkelWx Posted July 18, 2020 Share Posted July 18, 2020 Corn sweat is probably going to contribute to insane dewpoint readings Monday. Wouldn't be surprised to see a couple 80F dews here and there. 1 Link to comment Share on other sites More sharing options...

I’ve reported .98” in July, and .43” of that was reported on the 1st, so I’m really at about a half an inch for the month.

Was bone dry the 2 weeks prior, and the last 5+ days. Amazing how dry the soil is already, outside of where I have watered the past few days. 2 Link to comment Share on other sites More sharing options...

CAPE Posted July 18, 2020 Share Posted July 18, 2020 From Mount Holly AFD on rain potential mid week- Wednesday-Thursday... Most signs point to this being the most unsettled stretch of the extended period. Guidance is in good agreement that the stalled front will lift back north into the region for midweek. This will bring humid air surging back into any areas that dried out on Tuesday. Cloud cover in the vicinity of the boundary should keep a lid on temperatures for these days, but highs still look to approach 90 each day, which combined with the humidity will yield heat index values in the upper 90s to near 100. The bigger story for this period will probably end up being convection. Multiple convectively enhanced shortwaves will propagate along the stalled frontal boundary Wednesday and Thursday and serve as triggers for what could be multiple rounds of convection. Both low level and deep layer flow are modest, so am not overly concerned about severe weather outside of the usual gusty wind potential in stronger storm cores. However, setups like this often produce at least locally heavy rainfall, and suspect hydro will be an issue on one or both of these days. PWATs climb to near 2" on Wednesday and may be even higher Thursday at least to the south. This combined with very deep warm cloud layers argues for efficient rainfall production, and wind profiles are supportive of potential for training storms.

This is that thing where LWX dots every i and crosses every t for heat products... 104 heat index sorry y'all. I get it but it is funny to compare to svr as noted earlier in this thread. Watch they'll fill it in overnight or something. Link to comment Share on other sites More sharing options...
