CUCURBIT DOWNY MILDEW ipmPIPE

 

Cucurbit Downy Mildew Forecasts - Wednesday, October 26, 2016
 

*** Epidemic Update - 17 October: No new reports. Please view the Epidemic History for details. ***

*** Epidemic Update - 7 October: New report from OH. CDM has been confirmed in Stark County, OH. Please view the Epidemic History for details. ***

 

Regional Weather: Central & Eastern U.S. / southern Canada

Unsettled North; mostly dry South. A low pressure system traverses west to east across the northern tier, with rain / snow North and a few showers elsewhere. Mostly dry otherwise. Warm most locations with highs 60s to 80s, lows 40s to 60s, and cooler readings across portions of the North.

OUTLOOK:

Overview: Epidemic spread unlikely. The situation during midweek is similar to the one that occurred early-week. Cold temperatures and lack of host in the northern areas will keep risks very low. Host availability, scant chance of rain, and recent dry weather suppress the chances of epidemic spread in the southern areas.  

Risk prediction map for Day 1: Wednesday, October 26

Minimal Risk to cucurbits.

Risk prediction map for Day 2: Thursday, October 27

Minimal Risk to cucurbits.

*** Epidemic Update - 17 October: No new reports. Please view the Epidemic History for details. ***

*** Epidemic Update - 7 October: New report from OH. CDM has been confirmed in Stark County, OH. Please view the Epidemic History for details. ***

 

Regional Weather: Central & Eastern U.S. / southern Canada

Dry most regions. High pressure dominates the weather picture. Expect sunny to partly cloudy skies and little to no precipitation. Scattered showers are possible in a few locations. A developing system will bring rain to the north-central areas late Tuesday. Temperatures will vary greatly, with highs from the 40s to 80s and lows from the 20s to 60s.

OUTLOOK:

Overview: Epidemic spread highly unlikely. Temperatures are too cold through the North, where there's a chance of rain in some places. Elsewhere, unfavorable sky conditions and dry weather preclude any epidemic spread.  

Risk prediction map for Day 1: Monday, October 24

Minimal Risk to cucurbits.

Risk prediction map for Day 2: Tuesday, October 25

Regional Weather: Central & Eastern U.S. / southern Canada

Unsettled Northeast; mostly dry otherwise. A low pressure area in the Northeast anchors a cold front sweeping through the East. High pressure in the central U.S. follows, with drier weather and much cooler temperatures. Expect showers and rain today in the mid-Atlantic and Northeast. Rain will continue in the northeast U.S. / southern Canada Saturday and Sunday as the low pressure area lingers. Sunny to partly cloudy skies and dry nearly all other areas this weekend. There will be a very wide range of temperatures; highs in the 40s and 50s North to 70s and 80s South, lows mostly 30s and 40s with some 50s South.

OUTLOOK:

Overview: Epidemic spread unlikely. Mild and potentiallly wet weather near the East Coast today will generate some modest risk to cucurbits. Otherwise ... in the North, markedly colder temperatures will greatly diminish the chance for epidemic spread, despite the wet weather. Farther south and west, where the temperatures will be more suitable for epidemic spread, sky cover and potential for rain will be quite unfavorable.  

Risk prediction map for Day 1: Friday, October 21

Low Risk for cucurbits in northeast SC, eastern NC, southeast VA, eastern MD, DE, southeast PA, NJ, southeast NY, Long Island, CT, and western MA. Minimal Risk to cucurbits otherwise.

Risk prediction map for Day 2: Saturday, October 22

Minimal Risk to cucurbits.

Risk prediction map for Day 3: Sunday, October 23

Minimal Risk to cucurbits.

*** Epidemic Update - 7 October: New report from OH. CDM has been confirmed in Stark County, OH. Please view the Epidemic History for details. ***

 

Regional Weather: Central & Eastern U.S. / southern Canada

Unsettled Northeast and east-central U.S.; mostly dry elsewhere. An energetic pattern evolves as two fronts merge together in the east-central United States. Rain wil fall from the Northeast and Great Lakes southwestward to the Gulf Coast, mainly on Thursday. Much of the southeastern and central U.S. will be dry. Still quite warm with highs in the 60s to 80s, lows in the 40s to 60s.

OUTLOOK:

Overview: Epidemic spread possible many areas during Thursday's transport events. With only a few exceptions, Wednesday's transport events will involve too much solar exposure for much spore survival and/or any rain will arrive far too late in the night for much impact. Most of Thursday's events, many of which move near-source or northeast, will have more favorable conditions for epidemic spread.  

Risk prediction map for Day 1: Wednesday, October 19

Moderate Risk in southeast TX. Low Risk for cucurbits in central IL, southwest IN, northern KY, and southern OH. Minimal Risk to cucurbits otherwise.

Risk prediction map for Day 2: Thursday, October 20

Moderate Risk in southeast TX, central and northern MS, northern AL, TN, KY, and southern IN. Low risk for cucurbits in deep south TX, the NC mountains, far northeast TN, southwest VA, WV, central and northern IN, central and southern MI, OH, southern ON, northern MD, northern DE, PA, NY, Long Island, CT, western MA, and VT. Minimal Risk to cucurbits elsewhere.

Regional Weather: Central & Eastern U.S. / southern Canada

Mostly dry and warm. High pressure centered in the western Atlantic and extending over much of central and eastern North America governs the weather. A frontal system lies over the northern areas and southwestward into the Plains. Some showers will occur with the front as it moves east but rainfall amounts will not be great. A few showers are possible in the far South. Quite warm with highs in the 70s and 80s and lows in the 50s to 70s.

OUTLOOK:

Overview: Epidemic spread unlikely. Conditions are unfavorable for survivable transport and deposition in the large majority of cases each day. Slightly favorable conditions, at most, exist for some transport events in the North and FL. 

Risk prediction map for Day 1: Monday, October 17

Low Risk for cucurbits in northern FL, central and southern MI, northern OH, southern ON, western NY, and central and western PA. Minimal Risk to cucurbits otherwise.

Risk prediction map for Day 2: Tuesday, October 18

Low risk for cucurbits in southern FL, central and southern MI, northeast IN, southern ON, northern OH, northern PA, NY except the southeast, and VT. Minimal Risk to cucurbits elsewhere.
