You may want to monitor a potential marine heatwave in the north Pacific and discussion of its subsequent winter impact in the northeast USA. Long ranging is fraught with poor performance but the researchers and pattern relators attempt to Improve

Looks quite threatening from near White Plains into ne NJ. Here's a 5" report embedded within 4" near White Plains. I know NWS doesn't use these amounts but if you check the RadarScope STP...its AT LEAST 5" in that area near White Plains. Just an example. Click for. clarity on both graphics. I'm probably off line til 830P.

Good Monday morning everyone. Please follow anticipated NWS warnings-statements later today. Already as of 530AM 1/4-1/2" amounts fell earlier today in NNJ. Watches are posted where potential exists for localized excessive rainfall by Tuesday morning, isolated 5-6" totals possible, mainly NJ portion of our NYC subforum. An impaired Monday evening commute is anticipated with delays-accidents-possible detours. Plan accordingly. Recent humid but no rain scenario of past several days limits any mainstream flood potential but creeks-small streams, and especially urban areas along I95 are vulnerable to short fuse excessive rainfall, life threatening flooding if caught in overflowed roads. Turn around-don't drown should be in the back of all motorists minds. Added SPC HREF average rainfall and maximum potential rainfall graphic by Tuesday evening (most of this occurring 2PM-Midnight today). The WPC excessive rainfall forecast. Also the 5AM WPC 7 day rainfall anticipated by the 21st and depiction of NWS watches lager today.

No thread as of 609P/13 but since PHI has a Flood Watch posted..am leaning to an issuance as an OBS-NOW FF thread at 6A Monday... all of the above pertains. Will also look and see if I need to combine the wfront/qstry front additional for Tuesday. Have a good night.

No thread yet, but considering on for I95 corridor northwest across NNJ and se NYS for iso 5" in 3-6 hours Mon afternoon-Night. Will review more guidance late in the day and repost around 8P. 12z/13 SPC HREF is more or less mirroring the heavier GFS qpf. Am pretty sure the iso ~ 5" occurs but where?.

Wantage NJ 4sw... (8 s of High Point NJ) 347 PM report. Had about .36" in 11 minutes ending around 333 PM. Max G 25 MPH (higher than the previous 140PM warned storm). Very little T if any in this 323PM batch. Total for this afternoon now1.21", one tenth inch less than the automated Ambient gage.

Wantage NJ 1230-145P including the warned storm. Max G on my weather Stn 14... rainfall 0.85" in 75 minutes - 3 events.

Thought about a combined SVR-FF thread but HREF not as impressive with max qpf as prior threaded event. No doubt there will be iso 2-3" problems. Noted SPC conservative on SVR so for now...opted to leave all obs right here in the July thread. Will be offline most of the day.

No thread, at least not yet... but the week ahead seems like opportunity for mesoscale excesses. Many models disagree with the EPS (and occasionally the CMC suite) ever increasing heavy rain threat for parts of our NNJ portion of the NYC subforum. For now will go with 3" max Mon afternoon-evening somewhere up here-probably near I95. (Chantel 850 flow-moisture advection combined with RRQ of th UL jet over New England) Looking ahead...the CF heavy convection in parts of the area Tue. Then Thu-Fri, maybe Sat... heavy rain potential with southern stream short wave and warm front returning. Some of the experimental modeling has us in small chance iso FF THU-Sat (spot 5"+ this 3 day period). Added July CoCoRaHs totals as a baseline. Click for clarity. Next potential 3 day (dry) haying period around 7/16-19? Cleaned up the FF potential graphics at 752AM

So... unless I'm wrong, the pattern for summer is established. Weakness in the southern and eastern USA. Generally at or ABOVE normal temps around here. Next chance for FF opportunity in our NYC subforum seems to be in the July 8-15 time frame THOUGH AI seems to deny.

Agreed on premise. Too bad we have to be sarcastic and use CP as a cooling center. Powers that be have created the situation and for the diehards (point specific accuracy), not acceptable.

Southern edge of NYC subforum verified 5+. See attached. SVR was reserved for southern edge of our subforum - NJ. Two day totals attached as of 730AM July 2. (You can unpin whenever you want).

So far via weather underground 4.36 Asbury park and 4.13 Herbertsville...sough edge of our forum. That's today only. does not include anything last evening.

Dissapointing die off near I80 overnight, after 2+ near Trenton and apparently 1-1.5 parts of southeast LI earlier today. This afternoon-night should be active with mesoscale SVR/FF reports. Leftover rain Wed morning LI-NJ. I probably wont be back on til late today.

Added CPC July ... issued 6/30
