  1. Past hour
  2. I don’t see anyone getting to 90 all three days. But maybe.
  3. FYI Since we are talking about plants and flowers, I just got this ultraviolet pass filter to see hidden markings on flowers. More details can be found on this page: http://www.virtualherbarium.org/GardenViews/BeesEyeView.html Bees Eye View Scott Zona, Ph.D., Former Palm Biologist http://www.virtualherbarium.org/images/BeesEyeView5.jpg For some time, biologists have known that bees perceive light differently than humans do. What we see as visible light is a small portion of the electromagnetic spectrum and consists of a mixture of different colored light. Color is determined by the light's wavelength, which ranges from violet (400 nm wavelength) to red (700 nm). We are unable to see other portions of the spectrum, such as ultraviolet or infrared. Bees, on the other hand, see a portion of the spectrum shifted toward shorter wavelengths. Their eyes perceive yellows, greens, blues and purples as we do, but they also perceive ultraviolet (UV) light (180-400 nm). Bees do not perceive the red portion of the visible spectrum. http://www.virtualherbarium.org/images/BeesEyeView1.jpg What we see What the bee sees Because their eyes are so different from ours, we can only approximate how bees see flowers. By using photographic equipment, we can visualize some components of bee vision that are normally invisible to us, namely the reflection or absorption of UV radiation. Plants contain chemicals that either reflect or absorb electromagnetic radiation, including UV, visible, and infrared (which we cannot see but we can feel as heat). Sunlight's UV radiation is absorbed, partially absorbed, or reflected by flowers and can be captured on black and white photographic film or with a digital camera, using special filters. In the resulting photograph, reflected UV appears white, and absorbed UV appears dark. Partially absorbed UV appears gray. The two photos shown here are of a locally common weed, Achmella pilosa, in the sunflower family (Asteraceae). The photo on the left was taken in sunlight without any special filter, using a Minolta DiMAGE 7Hi digital camera. The right-hand photo was subsequently taken with a Wratten 18AUV filter attached to the camera. Typical of the sunflower family, Achmella has the common daisy-type “flower” (inflorescence) that is actually a group of two different kinds of flowers. The outer “petals” are individual flowers, called ray flowers. The central eye is a cluster of small flowers called disk flowers. Together, these two kinds of flowers make up the inflorescence we commonly call daisies or sunflowers. Achmella pilosa exhibits a common phenomenon seen in many Asteraceae: the bull's eye pattern formed by UV-reflecting ray flowers and UV-absorbing disk flowers. The pattern helps bees locate and land on the flowers. Plants need bees to carry pollen from one flower to another, and UV patterns expedite the process.
  4. They are far superior in my mind. The best ones come from the Indian/Atlantic ocean confluence, in waters about 400-500 feet, at temps around 45F. My GF is Dutch South African, and we go back every Feb/March for a few weeks. This year we spent a week with her family in Rustenburg, then drove for 2 days down to Cape Town- Camps Bay. Just down from our apartment is the Codfather restaurant. You pick the fresh seafood, and they prepare in front of you. I got 6 SA lobster tails, as usual. You can order them for delivery here, but it's almost less money to fly to SA to enjoy them.
  5. I didn't know it covered 250 acres and they have an Alice in Wonderland themed giant topiary going on there? I am partial to the giant March Hare topiary! Question-- why is it called New York Botanical Garden when it's in The Bronx? Why not call it The Bronx Botanical Garden? We have one in Brooklyn and it's called The Brooklyn Botanical Garden.
  6. last year on this very date it was 42 degrees lol
  7. wow it was 42 degrees here last year on this date? now thats cold!
  8. wow 2010 really rocked both spring and summer I want a weather modification device that just puts 2009-2011 on repeat forever. winter 2009-10, summer 2010, winter 2010-11 and summer 2011
  9. Today
  10. Maybe a heat wave In the typical hot spots this week?
  11. CoC incoming. Very warm temperatures are expected on Tuesday and Wednesday, with temperatures reaching into the 80s, with an outside chance a few locations see 90 degrees on Wednesday. Humidity levels will be on the low side accompanying that midweek warmth
  12. presence of moderate to heavy showers along the I-95 corridor that seemed to be driven by a SW to NE oriented 925mb jet (~30kt in strength) and moisture convergence between 925mb-850mb. Even the NAMNest, that was one of the only pieces of guidance that diagnosed more widespread, impactful rain on Saturday, struggled to depict the nocturnal rain
  13. Still raining. Or misery mist to be more accurate.
  14. Headed out crabbing this morning. I got up at 4:30 and heard water running through the gutters. There's nothing on radar. It's just a steady drizzle. I was hoping for a beautiful sunrise. Now I'm hoping for jumbo crabs. Screw the sunrise lol
  15. Either way, I don't understand SPC's lack of even a hatched area for any hazard on the Day 3 outlook...
  16. Having reviewed 00z guidance, it certainly looks interesting near western Oklahoma early Sunday evening. Models show troughing across the High Plains with subtle lee cyclogenesis over southwestern Kansas. A belt of enhanced upper level flow should reside from New Mexico across the OK/TX panhandles and into Kansas as the mid level wave ejects. Convective initiation seems likely by mid afternoon near an effective triple point over SW Kansas and with warm advection farther north in central/northern Kansas near a pseudo warmth front. Capping and initially larger T/Td dew point spreads along the dryline over the eastern Texas panhandle will delay convective initiation until late afternoon. With that said, most 00z CAMs show at least one or two isolated storms going up ahead of the dryline by 22-00z. If sustained convection is realized, any storm would move eastward, into western Oklahoma, where increasingly richer moisture will reside. This along with an increasing low level jet would conditionally favor intense supercell development and an associated tornado threat. Given that messy storm modes are more likely across Kansas, the southern target certainly has my attention. Especially given a southern stream perturbation pointing right at the dryline, just south of the surface low.
  17. Looks like west and north of Boone are getting hammered.
  18. Yeah I'll take the few showers we had today over what I've had to deal with the past few weeks.
  19. I do agree it is a very impressive shortwave and definitely bares some resemblance to 4-26-24. However, what are your thoughts on shear vector orientation to initiating boundary? Seemed like there was a less than 45 degree component esp to west but more orthogonal to the east. If you get a prefrontal trough could be a bigger tornado threat but wondering if storms fire off DL/pacific front if they will be more of a mixed mode of lines and embedded sups.
  20. Severe Storm hit at my home this afternoon producing dime size Hail and flooding. I measured 4.33" of Rainfall from the storm. 4.04" fell in an hour and 15 minutes . Numerous driveways washed out , mudslides aling with fallen Tree's. Some strong winds as well with downed limbs.
  21. Tuesday has big league severe possibilities in Iowa and surrounding area. Don't see many shortwaves with 500 mb flow approaching 90 kts (and relatively low amplitude) and 850 mb flow of 50+ kts this time of year. Has outbreak potential, especially if the trough slows a bit and we get a solution that resembles the last few runs of the ECMWF.
  22. Well we managed three below normal days (officially). I don’t really see many opportunities for below normal temps over the next 7-10 days. Looks well above normal through Wednesday, and then cooler but likely still above normal late next week into the start of the holiday weekend.
  23. Right. These dudes are all trolls.80/70 does not feel good no matter how you spin it
  24. It is not cold...at all haha
