‘Forecast’ weather update for October 21

Weather update for professional turf managers from Frank Rossi:

Temp & GDD

Another warmer than average week at almost 10(!) degrees warmer than normal in Western NY, scaling down to +4 degrees along coastal areas. Still accumulating GDDs. 50-90 from North to South in the region, with around 30-40 in Mass and New England. DC and Philly eclipsed 4000 GDD for the year, while NYC climbed above 3500. Most regions are around 200 GDD ahead of last
year, and 300-400 above normal. Soil temps still in the mid to upper 60’s.

Moisture

Another dry week for much of the region except some of Northern NY, areas received about 0.5” or precipitation. ET is predictably declining as well at about 0.5 “ or less for most regions. Drought areas not expanding but also not decreasing very much.

Forecast

Significant rainfall is expected for next week. Western and Central NY expected to get 2-3 inches. NYC, Boston and Eastern MA to get 1-1.5 inches, while NJ southward should expect about ½”. It is projected to be a cooler than average week for a change, with highs in the 50’s and low 60’s. Conflicting models for long term forecast-cool and wet likely.

‘Forecast’ weather update for October 3 – Long Season More Challenges

Weekly weather update for professional turf managers from Frank Rossi:

Temp & GDD

A long awaited return to seasonal temperature averages may have felt cold this past week. Western NY and Eastern PA were still 2-4 degrees above average.  Still accruing GDD, around 120 from NYC southward, and 60-80 in CNY and New England. Soil temps have begun to dip into the high 60’s in southern areas, with low to mid 60’s seen in Western NY and New England and even 50’s in Southern Tier and Albany.

Moisture

Another dry week for most of the region with most receiving <0.25”. Big winners continue to be to the south of the region with the DC area receiving 3” plus. ET remains fairly low so at least we are not losing as much moisture from the system until winds pick up. Drought areas continue to expand especially in coastal New England.

Forecast

Showery and overcast expected for week of 10/3. Potential of 2” in Long Island on up to Cape Cod while Upstate NY to Boston expect 1”. Temp’s projected to be above normal, especially overnight temps in the 50’s and 60’s. 8-14 day models have storm systems working up Atlantic Coast to perhaps NJ before heading East.

‘Forecast’ weather update for September 26 – Changing climate is forcing changes in long time recommendations

Weekly weather update for professional turf managers from Frank Rossi:

Temp & GDD

Eleven straight weeks of above normal temperatures. Most 4-6 degrees above normal, with particular stress along the I-95 corridor due to warmer nights. Still accumulating significant GDD numbers between 100-200 when normally NONE. Soil temps are still warm at 2” depth ranging from low to mid 70’s in Washington, to upper 60’s the central and upstate NY regions. This is the longest growing season in 17 years of ShortCUTT.

 

Moisture

Region wide rainfall amounts in general 1-2”, except swath through Central NY, HudValley, and Pioneer Valley where 0.25-0.5”. Soaking rain in South NJ and SW NY at 2” plus. ET is lower, at 0.6” in spite of warm weather, ET is driven primarily by solar radiation that is lower as sun moves down from peak angle.

Forecast

A very dry week expected with “normal” temps that will feel cold. Highs mid 60 – low 70’s. Overnights in the 40’s -50’s. Potential spotty frost on Monday with dry air lowering dew point at night.Atlantic Hurricane systems are not threatening. Long term models call for return to warm and dry for 8-14d outlook.

‘Forecast’ weather update for September 19 – Climate it is a changin’

Weekly weather update for professional turf managers from Frank Rossi:

Temp & GDD

Ten straight weeks of above normal temperatures, this week 6-8 above normal region wide. High heat stress and warm evening temps have really been keeping the stress on. Cool nights are more common further north that provide some relief. GDD continue to accumulate at record rates pushing us 2-3 weeks ahead of normal. Soils have cooled some into the low to mid 70’s but still very warm for this time of year.

The persistent warm weather certainly fuels the discussion regarding climate change effects on professional turfgrass and landscape management. We are on pace to end the season 300 plus GDD above normal, that amounts to additional 2-3 weeks of growing season.

Moisture

Another mostly dry week across the region wont most areas recording <0.25”. ET is still 0.75-1”. The lone winner for the week was extreme Western NY, Syracuse and Mohawk Valley with 1-2” plus in some areas. Drought conditions continue to expand in area affected and severity.

Forecast

Expect more warm weather with averages to be 9o above normal for the week. Upper 70’s to upper 80’s for highs lows 50-60 when normals are 60’s and 40’s. Some passing rainfall over the weekend leads us into a another mostly dry week. Topsoil moisture levels will continue to decline and low disease risk.

‘Forecast’ weather update for September 12 – It’s a record!

Weekly weather update for professional turf managers from Frank Rossi:

Temp & GDD

Nine weeks above normal temperatures with this week @2 above normal . Heat stress widespread and unusual GDD accumulation for this time of year continues to push the growing season longer than normal. Soils still warm at 2” depth in the upper 60’s and 70’s. August was the warmest in the Northeast in 122 years of recordkeeping by NOAA.

Moisture

Another unusually dry week with many receiving no measurable rainfall. The total northeast has seen a slight drop in area under drought, however the area amounts for many of the most severe levels of drought are increasing. ET this past week was 0.75-1.25” in some places. Very high for this time of season.

Forecast

Following an extremely warm weekend where temps soared to 20 degrees F above normal only to barely make it to the 70’s one day later. Expect more seasonable but still warm weather. Not much reliable widespread rain expected so expect dry conditions and high ET for next 8-14d. Disease risk,especially typical for Fall Dollar Spot expected to be low.

‘Forecast’ weather update for September 5

Weekly weather update for professional turf managers from Frank Rossi:

Temp & GDD

Two consecutive months of above normal temps and this week alone at 4-7 above normal region-wide. Heat stress persisted region-wide as well bringing unrelenting humidity into the evening. Soils have returned to warming as dry conditions persisted, into the upper 70’s for highs and upper 60’s in the north.

Moisture

A mostly dry week across the region except for a few spots of 0.5” in CNY, 1-2” in Buffalo. ET values very high for early September at 1-1.25” region-wide,  especially in areas that did not receive any rainfall. Drought monitor continues to indicate areas of abnormal and severe drought condiitons. USDA Topsoil moisture map also indicating more drying.

Forecast

Hot and dry conditions expected for much of the week with intense heat expected into the weekend. Early week chances of the remnants of Hermine hitting the Coast have lessened with some wind and low rainfall amounts expected. Temps expected in upper 80’s and 90’s , low upper 60’s and 70’s. High temp conditions expected to persist in the 8-14d outlook, keeping disease and heat stress pressure high.

‘Forecast’ weather update for August 29

Weekly weather update for professional turf managers from Frank Rossi:

Temp & GDD

The seventh straight week of above normal temps was not as severe as previous weeks coming in at 2 degrees F above normal. Heat stress was confined to the I-95 corridor and the Buffalo/Rochester areas. Soils have cooled slightly into the mid-low 70’s at 2” inch depth and likely much warmer where most of the plant roots are these days.

Moisture

Another week of widespread rainfall brought 1-2” to most areas with Central NY a big winner. Many other areas were <0.5” NJ, Hudson Valley and West NY, and <0.25” in eastern MA. ET 0.75-1”, somewhat slowed by high humidity. Last 14d have brought above normal precip. at 130-200% of normal for some areas Upstate NY. However 60 to 90 day deficits persisting.

Forecast

Expect a dry-warm (not hot) week about 6-8 degrees F above normal. A big cool down early in the week, especially night-time lows, will also bring lower humidity and more drying conditions. Rainfall likely to be very spotty with a more reliable front moving through by the end of the week. Long term starting to look at Tropical Storm activity and rainfall that could arrive.

Turf tech and ecosystem services

‘Flash’ talk by Frank Rossi, associate professor and turf specialist, Horticulture Section, School of Integrative Plant Science, Cornell University at the Horticulture Graduate Field Review
August 19, 2016:

‘Forecast’ weather update for August 22

Weekly weather update for professional turf managers from Frank Rossi:

Temp & GDD

Six straight weeks of above normal temps. Most were 8-10 F above normal with persistent heat stress with little relief in the evening hours. The start and stop and start of the growing season is warmer than last year and normal by a week. Soil temperatures are well into the 80’s at 2” north into the Hudson Valley. Upper 70’s most everywhere else. These temps at 2” suggest even warmer temps are likely in the top 1” where many annual bluegrass roots are confined.

Moisture

Widespread 1-2 inch rainfall with some 2’+ Catskills, ADK, NE CT. Many areas in Western NY did NOT benefit from the rainfall. Drought conditions have worsened for many but recent rainfall suggests severity levels might be changing soon. ET remained high at 0.75 – 1.25” with the rainfall and steamy days.

Forecast

Following another warm weekend, a pattern shift is expected to bring widespread rain and cooler night temperatures. Normal highs 70-80 lows 50-60! High pressure coming through so expect some low humidity days in already dry areas. The 8-14d suggests back to dry period with normal temps.
