Severe Weather Coordination Message #1 – Thursday May 28th 2015 Severe Weather Potential

May 28, 2015 Rob Macedo Leave a comment

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms possible to likely again today, Thursday, across much of interior Southern New England. The Storm Prediction Center, SPC, has placed much of interior Southern New England in a slight risk for severe weather with a marginal risk surrounding the slight risk area. Strong to damaging winds, hail and heavy rainfall with possible urban to poor drainage flooding are the primary threats. Threat timeframe is in the early to mid afternoon to early evening timeframe so a bit earlier than Wednesday and some interior areas of Eastern New England could be affected..
..SKYWARN Activation with Ops at NWS Taunton are likely later today and tonight..

Yesterday, portions of Western Massachusetts were impacted by strong to severe thunderstorms with strong to damaging winds as a trough swung through the area. As expected, activity weakened as it moved eastward. Below is the NWS Taunton Local Storm Report on the pockets of wind damage that occurred with the severe thunderstorms in Western Massachusetts as well as one lightning induced structure fire:

NWS Taunton Local Storm Report – Wednesday 5/27/15 Severe Weather Event:
http://kamala.cod.edu/offs/KBOX/1505272351.nwus51.html

For today, a cold front that will bring a bit cooler and less humid conditions will swing through Southern New England this afternoon and tonight. Wind shear values and instability values should be sufficient for isolated to scattered strong to severe thunderstorms across interior Southern New England starting as early as the first part of this afternoon and lasting through early evening. The key possible limiting factor is whether dry air at the mid-levels moves in and limits storm development. If that doesn’t occur, at minimum, isolated to scattered strong to severe thunderstorms will affect portions of interior Southern New England and extend into Eastern New England. The Storm Prediction Center, SPC, has placed much of interior Southern New England in a slight risk for severe weather with a marginal risk surrounding the slight risk area. Strong to damaging winds, hail and heavy rainfall with possible urban to poor drainage flooding are the primary threats.

SKYWARN Activation with Ops at NWS Taunton are likely later today and tonight. This will be the only complete coordination message on today’s severe weather potential. A shortened coordination message will be issued if time allows and Ops at NWS Taunton are initiated. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Severe Weather Coordination Message #2 – Wednesday May 27th 2015 Severe Weather Potential

May 27, 2015 Rob Macedo Leave a comment

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms remain possible across Western Massachusetts and Northwest Connecticut for later Wednesday Afternoon and Evening. Strong to Damaging Winds, Hail and Heavy Rainfall leading to possible urban and poor drainage flooding are the primary threats. The Storm Prediction Center (SPC) has placed this area in a Slight Risk for severe weather with a marginal risk for severe weather surrounding the slight risk area across Western Massachusetts and Northwest Connecticut. Threat timeframe is after 400 PM this afternoon through early evening..
..SKYWARN Activation with Ops at NWS Taunton will commence at 330 PM to monitor this potential across Western New England..

Warm and humid conditions will continue across Southern New England today. A trough will be moving across New York State during the day today and approach Eastern New York and Western New England during the late afternoon and into early evening. How far east the trough progresses during the day and the level of destabilization that will occur will affect the severe weather potential across Western New England for this Wednesday Afternoon and Evening. There will be sufficient heating through the day and wind fields will be reasonably sufficient that if the trough makes it far enough east through Eastern New York before sunset that isolated to scattered strong to severe thunderstorms can occur across Western Massachusetts and Northwest Connecticut with strong to damaging winds, hail and heavy rainfall leading to possible urban and poor drainage flooding as the primary threats. The Storm Prediction Center (SPC) has placed this area in a Slight Risk for severe weather with a marginal risk for severe weather surrounding the slight risk area across Western Massachusetts and Northwest Connecticut. Threat timeframe is after 400 PM this afternoon through early evening.

SKYWARN Activation with Ops at NWS Taunton will commence at 330 PM to monitor this potential across Western New England. This will be the only coordination message on Wednesday’s severe weather potential. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are possible across Western New England late Wednesday Afternoon into Wednesday Evening. Strong to Damaging Winds, hail and urban and poor drainage flooding are the primary threats. The Storm Prediction Center, SPC, has placed areas just to the west of the NWS Taunton Coverage area in a Slight Risk for severe weather with a marginal risk for severe weather designated for western New England in the NWS Taunton coverage area. The timeframe for any isolated to scattered strong to severe thunderstorms is after 3-4 PM Wednesday Afternoon..
..SKYWARN Activation with Ops at NWS Taunton are likely late Wednesday Afternoon through Wednesday Evening. A more complete coordination message will be issued Wednesday Morning detailing the severe weather potential for western New England. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook..

Severe Weather Coordination Message #2 – Tuesday May 19th 2015 Severe Weather Potential

May 19, 2015 Rob Macedo Leave a comment

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms remain possible Tuesday Afternoon and Evening across Western and Central Massachusetts and North-Central Connecticut particularly in the 4-10 PM timeframe. Strong to Damaging Winds and hail would be the primary threats. The Storm Prediction Center, SPC, has continued a marginal risk for severe weather for Tuesday in Western and Central Massachusetts and North-Central Connecticut. Threat will be contingent on heating and instability levels as well as the timing of the cold front through the area. Wind shear profiles and other parameters appear favorable at this time..
..SKYWARN Activation with Ops at NWS Taunton are possible Tuesday Afternoon and Evening..

At 715 AM, Doppler Radar showed showers over Central and Southern New England back into Eastern New York. These will move through the area this morning and are associated with a warm front. Behind this area of showers is some clearing ahead of a cold front that will move through the region late Tuesday Afternoon and Tuesday Night. Wind shear profiles will be favorable for isolated to scattered strong to possibly severe thunderstorms but the question will be the amount of clearing allowing for heating and instability over the area and this will likely limit the coverage of any strong to severe thunderstorms to an isolated to scattered nature over western and central Massachusetts and North-Central Connecticut. SPC continues a marginal risk for severe weather over this area. Across eastern areas of Southern New England, any thunderstorms are expected to be sub-severe as the storms weaken with the loss of any heating though this will be monitored.

SKYWARN Activation with Ops at NWS Taunton are possible Tuesday Afternoon and Evening. This will be the last complete coordination message on this situation. A shortened coordination message will be posted if time allows and ops at NWS Taunton are initiated. Below is the NWS Taunton Hazardous Weather Outlook and the SPC Day-1 Convective Outlook.

Severe Weather Coordination Message #2 – Tuesday May 12th 2015 Severe Weather Potential

May 12, 2015 Rob Macedo Leave a comment

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms Remain Possible this Tuesday Afternoon and Evening Across much of Southern New England, particularly interior locations. Strong to damaging winds, hail and heavy rainfall are the primary threats. The Storm Prediction Center (SPC) has maintained a marginal risk for severe thunderstorms for much of Southern New England..
..SKYWARN Activation with Ops at NWS Taunton are possible today to monitor any potential strong to severe thunderstorms..

Today will be the last day of above normal temperatures until the end of this week as a cold front will sweep through the region this Tuesday Afternoon and Evening. Wind Shear profiles are quite strong in the mid to upper levels of the atmosphere. The key item with regard to the coverage and intensity of any strong to severe thunderstorms today is the amount of moisture in the atmosphere. Conditions this morning will be quite moist but will dry out a bit as the day progresses but weather models do show a return of some moisture values in the afternoon and early evening. Sufficient heating is expected today with the sun breaking out over the region particularly away from the immediate coast later this morning through this afternoon as the cold front and an impulse with the front move through the region. This will set the stage for isolated to scattered strong to severe thunderstorms this afternoon and evening with strong to damaging winds, hail and heavy rainfall as the main threats. SPC has maintained a marginal risk for severe thunderstorms for much of Southern New England. Again, the coverage is uncertain. There could be little to any strong to severe thunderstorms, to a few isolated strong and/or severe thunderstorms to more of a line of strong to severe thunderstorms depending on the available moisture the cold front and impulse has to trigger activity.

SKYWARN Activation with Ops at NWS Taunton are possible today to monitor any potential strong to severe thunderstorms that develop in the region. This will be the last complete coordination message on this potential. A shortened coordination message will be issued as time allows and if Ops at NWS Taunton are initiated. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
