Weather elements and forecast projections of proposed MRF-based guidance products. Projections are given in hours after the initial cycle time of 0000 UTC. The third column indicates the status of the weather element as compared to the current operational MRF MOS guidance.

Element | Forecast Projections | Status | Comments |

Max Temp | 24 - 192,
every 24 hrs |
Same | Daytime Maximum
(7 a.m. - 7 p.m. LST) |

Min Temp | 36 - 180,
every 24 hrs |
Same | Nighttime Minimum
(7 p.m. - 8 a.m. LST) |

Temperature | 12 - 192,
every 6 hrs |
New | 2-m Shelter Temperature |

Dew Point | 12 - 192,
every 6 hrs |
New | 2-m Shelter Temperature |

PoP (12-h) | 24 - 192,
every 12 hrs |
Same | Probability of > 0.01 inches of liquid-
equivalent precipitation during a 12-h
period. |

PoP (24-h) | 36 - 192,
every 12 hrs; new system provides 24-h PoP ending at both 0000 and 1200 UTC. |
Change | Probability of > 0.01 inches of liquid-
equivalent precipitation during a 24-h
period. Current system combines
12-h PoP to get 24-h PoP; new
system predicts
24-h value directly. |

PQPF (12-h) | 24 - 156,
every 12 hrs |
New | Probability of > 0.10, 0.25, 0.50,
1.00, and 2.00 inches during a 12-h
period.
Categorical precipitation amount. |

PQPF (24-h) | 36 - 156,
every 12 hrs; 24-h PQPF ending at both 0000 and 1200 UTC. |
New | Probability of > 0.10, 0.25, 0.50,
1.00, 2.00, and 3.00 inches during a
24-h period. Categorical precipitation
amount. |

Wind | 24 - 192, every 12 hrs | Change | Current system predicts the mean
wind over 12-h period; new system
will provide the probability of the
maximum wind during the 12-h
period falling into three categories: <
10 kts, 11 - 21 kts, > 22 kts as well as
a categorical forecast. |

Clouds | 24 - 192, every 12 hrs | Change | Current system predicts the mean cloudiness over a 12-h period; new system will provide the probability of the average total sky cover falling into three categories: mostly clear, partly cloudy, and mostly overcast. The corresponding categorical forecast will be indicated in the message by CL, PC, OV. |

PTYPE | 24 - 192, every 12 hrs | Change | Current system predicts the conditional probability of snow; new system will include the conditional probabilty of freezing, frozen, liquid, or mixed liquid/frozen precipitation as well as a categorical forecast. |
